Attributes
QName Type Fixed Default Use Annotation
atomID atomRefArrayType optional
<h:div class="summary">An array of atom IDs.</h:div>
<h:div class="description">Normally an attribute of an array-based element.</h:div>
convention refType optional
<h:div class="summary">A reference to a convention.</h:div>
<h:div class="description">There is no controlled vocabulary for conventions, but the author must ensure that the semantics are openly available and that there are mechanisms for implementation. The convention is inherited by all the subelements, 
so that a convention for
  <h:tt>molecule</h:tt>would by default extend to its
  <h:tt>bond</h:tt>and
  <h:tt>atom</h:tt>children. This can be overwritten
    if necessary by an explicit
  <h:tt>convention</h:tt>.
  <h:p>It may be useful to create conventions with namespaces (e.g.
    <h:tt>iupac:name</h:tt>).
    Use of
    <h:tt>convention</h:tt>will normally require non-STMML semantics, and should be used with
    caution. We would expect that conventions prefixed with "ISO" would be useful,
    such as ISO8601 for dateTimes.</h:p>
  <h:p>There is no default, but the conventions of STMML or the related language (e.g. CML) will be assumed.</h:p>
</h:div>
<h:div class="example" id="ex" href="convGroup1.xml"/>
count countArrayType optional
<h:div class="summary">Array of object counts.</h:div>
<h:div class="description">No fixed semantics or default, normally integral. It is presumed that the element can be multiplied by the count value.</h:div>
dictRef namespaceRefType optional
<h:div class="summary">A reference to a dictionary entry.</h:div>
<h:div class="description">Elements in data instances such as _scalar_ may have a
  <h:tt>dictRef</h:tt>attribute to point to an entry in a dictionary. To avoid excessive use of (mutable) filenames and URIs we recommend a namespace prefix, mapped to a namespace URI in the normal manner. In this case, of course, the namespace URI must point to a real XML document containing _entry_ elements and validated against STMML Schema.
  <h:p>Where there is concern about the dictionary becoming separated from the document the dictionary entries can be physically included as part of the data instance and the normal XPointer addressing mechanism can be used.</h:p>
  <h:p>This attribute can also be used on _dictionary_ elements to define the namespace prefix</h:p>

<h:div class="example" href="dictRefGroup1.xml"/>

elementType elementTypeArrayType optional
<h:div class="summary">The identity of a chemical element.</h:div>
<h:div class="description">Normally mandatory on _atom_, _isotope_, etc.</h:div>

<h:div class="summary">An array of formalCharges.</h:div>
<h:div class="description">Used in CML2 Array mode. NOT the calculated charge or oxidation state. No formal defaults, but assumed to be zero if omitted. It may become good practice to include it.</h:div>
hydrogenCount hydrogenCountArrayType optional
<h:div class="summary">Array of hydrogenCounts.</h:div>
<h:div class="description">Normally used in CML2 array mode. The total number of hydrogens bonded to the atom or molecule. It is preferable to include hydrogens explicitly, and where this is done their count represents the minimum (and may thus override this attribute). It is dangerous to use this attribute for electron-deficient molecules (e.g. diborane) or hydrogen bonds. There is NO DEFAULT and the absence of this attribute must not be given any meaning.</h:div>
id idType optional
<h:div class="summary">A unique ID for an element.</h:div>
<h:div class="description">Id is used for machine identification of elements and
                in general should not have application semantics. It is similar to the XML ID type
                as containing only alphanumerics, '_', ',' and '-' and and must start with an
                alphabetic character. Ids are case sensitive. Ids should be unique within local scope,
                thus all atoms within a molecule should have unique ids, but separated molecules within a 
                document (such as a published article) might have identical ids. Software
                should be able to search local scope (e.g. all atoms within a molecule). 
                However this is under constant review.</h:div>
occupancy occupancyArrayType optional
<h:div class="summary">Array of occupancies.</h:div>

  <h:tt>ref</h:tt>modifies an element into a reference to an existing element of that type within the document. This is similar to a pointer and it can be thought of a strongly typed hyperlink. It may also be used for "subclassing" or "overriding" elements.
  <br xmlns=""/>When referring to an element most of the "data" such as attribute values and element content will be on the full instantiated element.  Therefore ref (and possibly id) will normally be the only attributes on the pointing element.

<h:div class="summary">An atomType.</h:div>
<h:div class="description">
  <h:p>atomTypes are used in a wide variety of ways in computational chemistry. 
                They are normally labels added to existing atoms (or dummy atoms) 
                in the molecule and have a number of defined properties. 
                These properties are usually in addition to those deducible from the 
                elementType of the atom. AtomTypes usually depend on the chemical or 
                geometrical environment of the atom and are frequently assigned by 
                algorithms with chemical perception. However they are often frequently 
                set or "tweaked" by humans initiating a program run.</h:p>
  <h:p>AtomTypes on an atom have no formal relation to its
    <h:tt>elementType</h:tt>, 
                which only describe the number of protons in the nucleus. It is not unknown 
                (though potentially misleading) to use an "incompatible" atomType to 
                alter the computational properties of an atom (e.g. pretend this K+ 
                is a Ca++ to increase its effective charge).
    <h:tt>atomTypes</h:tt>will also be required to describe pseudoAtoms such as "halogen" 
                (generic) or "methyl group" (unified atom). Atoms in computations 
                can therefore have an
    <h:tt>atomType</h:tt>child with a "ref" 
                attribute.</h:p>
  <h:p>An atomType contains numeric or other quantities associated with 
                it (charges, masses, use in force-fields, etc.) and also description 
                of any perception algorithms (chemical and/or geometrical) which could 
                be used to compute or constrain it. This is still experimental.</h:p>
  <h:p>atomTypes are referred to by their mandatory
    <h:tt>name</h:tt>attribute. An atom refers to one or more atomTypes through 
                atomType/@ref children</h:p>

      <h:div class="description">
        <h:p>atomTypes are used in a wide variety of ways in computational chemistry. 
                They are normally labels added to existing atoms (or dummy atoms) 
                in the molecule and have a number of defined properties. 
                These properties are usually in addition to those deducible from the 
                elementType of the atom. AtomTypes usually depend on the chemical or 
                geometrical environment of the atom and are frequently assigned by 
                algorithms with chemical perception. However they are often frequently 
                set or "tweaked" by humans initiating a program run.</h:p>
        <h:p>AtomTypes on an atom have no formal relation to its
          <h:tt>elementType</h:tt>, 
                which only describe the number of protons in the nucleus. It is not unknown 
                (though potentially misleading) to use an "incompatible" atomType to 
                alter the computational properties of an atom (e.g. pretend this K+ 
                is a Ca++ to increase its effective charge).
          <h:tt>atomTypes</h:tt>will also be required to describe pseudoAtoms such as "halogen" 
                (generic) or "methyl group" (unified atom). Atoms in computations 
                can therefore have an
          <h:tt>atomType</h:tt>child with a "ref" 
                attribute.</h:p>
        <h:p>An atomType contains numeric or other quantities associated with 
                it (charges, masses, use in force-fields, etc.) and also description 
                of any perception algorithms (chemical and/or geometrical) which could 
                be used to compute or constrain it. This is still experimental.</h:p>
        <h:p>atomTypes are referred to by their mandatory
          <h:tt>name</h:tt>attribute. An atom refers to one or more atomTypes through 
                atomType/@ref children</h:p>

Attributes
QName Type Fixed Default Use Annotation
chirality chiralityType optional
<h:div class="summary">The chirality of a system or molecule.</h:div>
<h:div class="description">This is being actively investigated by a IUPAC committee (2002) so the convention is likely to change. No formal default.</h:div>
convention refType optional
<h:div class="summary">A reference to a convention.</h:div>
<h:div class="description">There is no controlled vocabulary for conventions, but the author must ensure that the semantics are openly available and that there are mechanisms for implementation. The convention is inherited by all the subelements, 
so that a convention for
  <h:tt>molecule</h:tt>would by default extend to its
  <h:tt>bond</h:tt>and
  <h:tt>atom</h:tt>children. This can be overwritten
    if necessary by an explicit
  <h:tt>convention</h:tt>.
  <h:p>It may be useful to create conventions with namespaces (e.g.
    <h:tt>iupac:name</h:tt>).
    Use of
    <h:tt>convention</h:tt>will normally require non-STMML semantics, and should be used with
    caution. We would expect that conventions prefixed with "ISO" would be useful,
    such as ISO8601 for dateTimes.</h:p>
  <h:p>There is no default, but the conventions of STMML or the related language (e.g. CML) will be assumed.</h:p>
</h:div>
<h:div class="example" id="ex" href="convGroup1.xml"/>
count positiveNumberType optional
<h:div class="summary">The count of the object.</h:div>
<h:div class="description">No fixed semantics or default, normally integers. 
                It is presumed that the element can be multiplied by the count value.</h:div>
dictRef namespaceRefType optional
<h:div class="summary">A reference to a dictionary entry.</h:div>
<h:div class="description">Elements in data instances such as _scalar_ may have a
  <h:tt>dictRef</h:tt>attribute to point to an entry in a dictionary. To avoid excessive use of (mutable) filenames and URIs we recommend a namespace prefix, mapped to a namespace URI in the normal manner. In this case, of course, the namespace URI must point to a real XML document containing _entry_ elements and validated against STMML Schema.
  <h:p>Where there is concern about the dictionary becoming separated from the document the dictionary entries can be physically included as part of the data instance and the normal XPointer addressing mechanism can be used.</h:p>
  <h:p>This attribute can also be used on _dictionary_ elements to define the namespace prefix</h:p>
</h:div>
<h:div class="example" href="dictRefGroup1.xml"/>

formalCharge formalChargeType optional
<h:div class="summary">The formalCharge on the object.</h:div>
<h:div class="description">NOT the calculated charge or oxidation state. No formal default, but assumed to be zero if omitted. It may become good practice to include it.</h:div>
formula formulaType optional
<h:div class="summary">Simple chemical formula.</h:div>
<h:div class="general">This attribute should only be used for simple formulae (i.e. without brackets or other nesting for which a _formula_ child element should be used. The attribute might be used as a check on the child elements or for ease of representation. Essentially the same as _concise_ attribute on _formula.</h:div>
id idType optional
<h:div class="summary">A unique ID for an element.</h:div>
<h:div class="description">Id is used for machine identification of elements and
                in general should not have application semantics. It is similar to the XML ID type
                as containing only alphanumerics, '_', ',' and '-' and and must start with an
                alphabetic character. Ids are case sensitive. Ids should be unique within local scope,
                thus all atoms within a molecule should have unique ids, but separated molecules within a 
                document (such as a published article) might have identical ids. Software
                should be able to search local scope (e.g. all atoms within a molecule). 
                However this is under constant review.</h:div>
idgen xsd:string optional
<h:div class="summary">Allows a referring element to generate a unique id.</h:div>
<h:div class="description">idgen can hold a unique identifier which is copied into the id
                attribute of the referenced element. This avoids multiple copies of the referenced 
                object with duplicate ids. EXPERIMENTAL</h:div>
<h:div class="curation">2006-05-22: PMR added.</h:div>
process xsd:string optional
<h:div class="summary">Keyword signifying how object is to be processed.</h:div>
<h:div class="description">Semantics depend on the parent element</h:div>
<h:div class="curation">2006-05-20: PMR added</h:div>
ref refType optional
<h:div class="summary">A reference to an element of given type.</h:div>
<h:div class="description">
  <h:tt>ref</h:tt>modifies an element into a reference to an existing element of that type within the document. This is similar to a pointer and it can be thought of a strongly typed hyperlink. It may also be used for "subclassing" or "overriding" elements.
  <br xmlns=""/>When referring to an element most of the "data" such as attribute values and element content will be on the full instantiated element.  Therefore ref (and possibly id) will normally be the only attributes on the pointing element. However there may be some attributes (title, count, etc.) which have useful semantics, but these are element-specific</h:div>
<h:div class="example" href="refGroup1.xml"/>
role xsd:string optional
<h:div class="summary">Role of the object.</h:div>
<h:div class="description">How the object functions or its position in the architecture. No controlled vocabulary.</h:div>
spinMultiplicity xsd:positiveInteger optional
<h:div class="summary">Spin multiplicity.</h:div>
<h:div class="description">Normally for a molecule. This attribute gives the spin multiplicity of the molecule and is independent of any atomic information. No default, and it may take any positive integer value (though values are normally between 1 and 5.</h:div>
symmetryOriented xsd:boolean optional
<h:div class="summary">Is the molecule oriented to the symmetry</h:div>
<h:div class="description">No formal default, but a molecule is assumed to be oriented according to any _symmetry_ children. This is required for crystallographic data, but some systems for isolated molecules allow specification of arbitrary Cartesian or internal coordinates, which must be fitted or refined to a prescribed symmetry. In this case the attribute value is false.</h:div>
title xsd:string optional
<h:div class="summary">A title on an element.</h:div>

<h:div class="summary">A reference to a convention.</h:div>
<h:div class="description">There is no controlled vocabulary for conventions, but the author must ensure that the semantics are openly available and that there are mechanisms for implementation. The convention is inherited by all the subelements,

  <h:p>It may be useful to create conventions with namespaces (e.g.

    Use of

<h:div class="summary">A homogenous 1 dimensional array of similar object.</h:div>
<h:div class="description">These can be encoded as strings (i.e. XSD-like datatypes) and are concatenated as string content. The size of the array should always be >= 1. The default delimiter is whitespace. The _normalize-space()_ function of XSLT could be used to normalize all whitespace to single spaces and this should not affect the value of the array elements. To extract the elements __java.lang.StringTokenizer__ could be used. If the elements themselves contain whitespace then a different delimiter must be used and is identified through the
  <h:tt>delimiter</h:tt>attribute. This method is mandatory if it is required to represent empty strings. If a delimiter is used it MUST start and end the array - leading and trailing whitespace is ignored. Thus
  <h:tt>size+1</h:tt>occurrences of the delimiter character are required. If non-normalized whitespace is to be encoded (e.g. newlines, tabs, etc) you are recommended to translate it character-wise to XML character entities.
  <h:p>Note that normal Schema validation tools cannot validate the elements
         of

Used by
Attributes
QName Type Fixed Default Use Annotation
constantToSI xsd:double optional
<h:div class="summary">Additive constant to generate SI equivalent.</h:div>
<h:div class="description">The amount to add to a quantity in non-SI units to convert its representation to SI Units. This is applied *after* multiplierToSI. It is necessarily zero for SI units.</h:div>
convention refType optional
<h:div class="summary">A reference to a convention.</h:div>
<h:div class="description">There is no controlled vocabulary for conventions, but the author must ensure that the semantics are openly available and that there are mechanisms for implementation. The convention is inherited by all the subelements, 
so that a convention for
  <h:tt>molecule</h:tt>would by default extend to its
  <h:tt>bond</h:tt>and
  <h:tt>atom</h:tt>children. This can be overwritten
    if necessary by an explicit
  <h:tt>convention</h:tt>.
  <h:p>It may be useful to create conventions with namespaces (e.g.
    <h:tt>iupac:name</h:tt>).
    Use of
    <h:tt>convention</h:tt>will normally require non-STMML semantics, and should be used with
    caution. We would expect that conventions prefixed with "ISO" would be useful,
    such as ISO8601 for dateTimes.</h:p>
  <h:p>There is no default, but the conventions of STMML or the related language (e.g. CML) will be assumed.</h:p>
</h:div>
<h:div class="example" id="ex" href="convGroup1.xml"/>
dataType dataTypeType optional
<h:div class="summary">The data type of the object.</h:div>
<h:div class="description">Normally applied to scalar/array 
                objects but may extend to more complex one.</h:div>
delimiter delimiterType optional
<h:div class="summary">A delimiter character for arrays and matrices.</h:div>
<h:div class="description">By default array components ('elements' in the non-XML sense) are whitespace-separated. This fails for components with embedded whitespace or missing completely:
  <h:pre>Example:
        In the protein database ' CA' and 'CA' are different atom types, and and array could be:
        <array delimiter="/" dictRef="pdb:atomTypes">/ N/ CA/CA/ N/</array></h:pre>Note that the array starts and ends with the delimiter, which must be chosen to avoid accidental use. There is currently no syntax for escaping delimiters.</h:div>
dictRef namespaceRefType optional
<h:div class="summary">A reference to a dictionary entry.</h:div>
<h:div class="description">Elements in data instances such as _scalar_ may have a
  <h:tt>dictRef</h:tt>attribute to point to an entry in a dictionary. To avoid excessive use of (mutable) filenames and URIs we recommend a namespace prefix, mapped to a namespace URI in the normal manner. In this case, of course, the namespace URI must point to a real XML document containing _entry_ elements and validated against STMML Schema.
  <h:p>Where there is concern about the dictionary becoming separated from the document the dictionary entries can be physically included as part of the data instance and the normal XPointer addressing mechanism can be used.</h:p>
  <h:p>This attribute can also be used on _dictionary_ elements to define the namespace prefix</h:p>
</h:div>
<h:div class="example" href="dictRefGroup1.xml"/>

end xsd:string optional
<h:div class="summary">The end value.</h:div>
<h:div class="description">The end value in any allowable XSD representation 
                of data.</h:div>

<h:div class="summary">Basis of the error estimate.</h:div>
<h:div class="description"/>
errorValueArray errorValueArrayType optional
<h:div class="summary">Array of error values.</h:div>
<h:div class="description">Reports the author's estimate of 
					the error in an array of values. Only meaningful for 
					dataTypes mapping to real number.</h:div>
id idType optional
<h:div class="summary">A unique ID for an element.</h:div>
<h:div class="description">Id is used for machine identification of elements and
                in general should not have application semantics. It is similar to the XML ID type
                as containing only alphanumerics, '_', ',' and '-' and and must start with an
                alphabetic character. Ids are case sensitive. Ids should be unique within local scope,
                thus all atoms within a molecule should have unique ids, but separated molecules within a 
                document (such as a published article) might have identical ids. Software
                should be able to search local scope (e.g. all atoms within a molecule). 
                However this is under constant review.</h:div>
maxValueArray floatArrayType optional
<h:div class="summary">Maximum values for numeric _matrix_ or _array.</h:div>
<h:div class="description">A whitespace-separated list of the same length as the array in the parent element.</h:div>
minValueArray floatArrayType optional
<h:div class="summary">Minimum values for numeric _matrix_ or _array.</h:div>
<h:div class="description">A whitespace-separated lists of the same length as the array in the parent element.</h:div>
multiplierToSI xsd:double optional
<h:div class="summary">Multiplier to generate SI equivalent.</h:div>
<h:div class="description">The factor by which the non-SI unit should be multiplied to convert a quantity to its representation in SI Units. This is applied *before* _constantToSI_. Necessarily unity for SI unit.</h:div>
ref refType optional
<h:div class="summary">A reference to an element of given type.</h:div>
<h:div class="description">
  <h:tt>ref</h:tt>modifies an element into a reference to an existing element of that type within the document. This is similar to a pointer and it can be thought of a strongly typed hyperlink. It may also be used for "subclassing" or "overriding" elements.
  <br xmlns=""/>When referring to an element most of the "data" such as attribute values and element content will be on the full instantiated element.  Therefore ref (and possibly id) will normally be the only attributes on the pointing element. However there may be some attributes (title, count, etc.) which have useful semantics, but these are element-specific</h:div>
<h:div class="example" href="refGroup1.xml"/>
size sizeType optional

<h:div class="summary">A parameter describing the computation.</h:div>
<h:div class="description">
  <h:p>A parameter is a broad concept and can describe numeric quantities, objects, 
                keywords, etc. The distinction between keywords and parameters is often fuzzy. 
                ("MINIM" might mean "minimize", while "MINIM=3" might require  three iterations 
                to be run. It may help to think of control keywords as boolean parameters.</h:p>
  <h:p>Numeric parameters can describe values in molecules, forcefields or other 
                objects. Often the parameters will be refined or otherwise varied during the 
                calculation. Some parameters may be fixed at particular values or relaxed at different 
                stages in the calculation.  Parameters can have errors, gradients and other indications 
                of uncertainty.</h:p>
  <h:p>String/character parameters are often abbreviated in program input, and this 
                is supported through the
    <h:tt>regex</h:tt>and
    <h:tt>ignoreCase</h:tt>attributes. ?????</h:p>
  <h:p>Parameters will usually be defined separately from the objects and use the
    <h:tt>ref</h:tt>attribute to reference them.</h:p>
  <h:p>Parameters can be used to describe additional constraints. This will probably 
                require the development of a microlanguage and until then may use program-specific 
                mechanisms. A common approach will be to use an array of values (or objects) to 
                represent different input values for (parts of) the calculation. Thus a conformational 
                change could be specified by an array of several torsion angles.</h:p>
  <h:p>A parameter will frequently have a

<h:div class="description">
  <h:p>
    <h:tt>symmetry</h:tt>provides a label and/or symmetry operations for molecules
         or crystals. Point and spacegroups can be specified by strings, though these are not 
         enumerated, because of variability in syntax (spaces, case-sensitivity, etc.),
         potential high symmetries (e.g. TMV disk is D17) and
         non-standard spacegroup settings. Provision is made for explicit symmetry operations
         through <matrix> child elements.</h:p>
  <h:p>By default the axes of symmetry are defined by the symbol - thus C2v requires
         z to be the unique axis, while P21/c requires b/y. Spacegroups imply the semantics
         defined in International Tables for Crystallography, (Int Union for Cryst., Munksgaard).
         Point groups are also defined therein.</h:p>
  <h:p>The element may also be used to give a label for the symmetry species (irreducible
         representation) such as "A1u" for a vibration or orbital.</h:p>
  <h:p>The matrices should be 3x3 for point group operators and 3x4 for spacegroup operators.
         The use of crystallographic notation ("x,1/2+y,-z") is not supported - this would
         be <matrix>1 0 0 0.0   0 1 0 0.5  0 0 1 0.0<matrix>.</h:p>
  <h:p>The default convention for point group symmetry is
    <h:tt>Schoenflies</h:tt>and for
         spacegroups is "H-M". Other conventions (e.g. "Hall") must be specfied through
         the

  <h:p>This element implies that the Cartesians or fractional coordinates in a molecule
         are oriented appropriately. In some cases it may be useful to specify the symmetry of
         an arbitarily oriented molecule and the <molecule> element has the attribute
    <h:tt>symmetryOriented</h:tt>for this purpose.</h:p>
  <h:p>It may be better to use transform3 to hold the symmetry as they have fixed shape and
         have better defined mathematical operators.</h:p>

    <h:tt>formula</h:tt>are nestable so that aggregates (e.g. hydrates,
        salts, etc.) can be described. CML does not require that formula information
        is consistent with (say) crystallographic information; this allows for
        experimental variance.</h:p>
  <h:p>An alternative briefer representation is also available through the
    <h:tt>concise</h:tt>. This must include whitespace round all elements and 
        their counts, which must be explicit.</h:p>
  <h:p>2005-10-16. The semantics are now the following. A formula must have one or both:
    <h:ul>
      <h:li>A concise attribute</h:li>A single atomArray child, using array format.</h:ul>it must also have a formalCharge attribute if atomArray is used and the charge is non-zero.</h:p>
  <h:p>The concise, formalCharge and atomArrary information must always be consistent and software should
	        throw an error if not.</h:p>
  <h:p>Until now there was no way of holding inline formula other than concise (although JUMBO5.0 is
	        capable of reading them). We now extend formula.xsd to incorporate this through the attribute
	        "inline" which requires the use of the "convention" attribute. The contents of inline are
	        purely textual. It can be used with or without atomArray or concise but there is no 
	        guarantee that it can be interpreted as a meaningful chemical formula or that there is consistency.
	        In some cases a document supplies several formula representations (e.g. the IUCr's CIF). In this
	        case a molecule (or crystal) element might contain several formula children. The semantics of which
	        to use are application dependent.</h:p>

          <h:tt>formula</h:tt>are nestable so that aggregates (e.g. hydrates,
        salts, etc.) can be described. CML does not require that formula information
        is consistent with (say) crystallographic information; this allows for
        experimental variance.</h:p>
        <h:p>An alternative briefer representation is also available through the
          <h:tt>concise</h:tt>. This must include whitespace round all elements and 
        their counts, which must be explicit.</h:p>
        <h:p>2005-10-16. The semantics are now the following. A formula must have one or both:
          <h:ul>
            <h:li>A concise attribute</h:li>A single atomArray child, using array format.</h:ul>it must also have a formalCharge attribute if atomArray is used and the charge is non-zero.</h:p>
        <h:p>The concise, formalCharge and atomArrary information must always be consistent and software should
	        throw an error if not.</h:p>
        <h:p>Until now there was no way of holding inline formula other than concise (although JUMBO5.0 is
	        capable of reading them). We now extend formula.xsd to incorporate this through the attribute
	        "inline" which requires the use of the "convention" attribute. The contents of inline are
	        purely textual. It can be used with or without atomArray or concise but there is no 
	        guarantee that it can be interpreted as a meaningful chemical formula or that there is consistency.
	        In some cases a document supplies several formula representations (e.g. the IUCr's CIF). In this
	        case a molecule (or crystal) element might contain several formula children. The semantics of which
	        to use are application dependent.</h:p>

To avoid excessive use of (mutable) filenames and URIs we recommend a namespace prefix, mapped to a namespace URI in the normal manner. In this case, of course, the namespace URI must point to a real XML document containing _entry_ elements and validated against STMML Schema.
  <h:p>Where there is concern about the dictionary becoming separated from the document the dictionary entries can be physically included as part of the data instance and the normal XPointer addressing mechanism can be used.</h:p>

                The dictionaryPrefix is normally unbound but it may be necessary to hardcode them

            Two dimensions are of the same type if their 'name' attributes are (case-sensitive) 
            identical. Dimensions of the same typecan be algebraically combined using the 'power' attributes.
            Normally dimensions will be aggregated and cancelled algebraically, but the 'preserve'
            attribute can be used to prevent this. Thus a velocity gradient over length can be 
            defined as:

            Two dimensions are of the same type if their 'name' attributes are (case-sensitive)

            Normally dimensions will be aggregated and cancelled algebraically, but the 'preserve'

<h:div class="summary">A scientific unit.</h:div>
<h:div class="description">
  <h:p>A scientific unit. Units are of the following types:</h:p>
  <h:ul>
    <h:li>SI Units. These may be one of the seven fundamental types 
        (e.g. meter) or may be derived (e.g. joule). An SI unit is 
        identifiable because it has no parentSI attribute and will have
        a unitType attribute. 2005-122-17 - this may be obsolete; PMR</h:li>
    <h:li>nonSI Units. These will normally have a parent SI unit
        (e.g. calorie has joule as an SI parent).</h:li>
    <h:li>Constructed units. These use a syntax of the form:
      <h:pre><unit id="g.s-1" name="gram per second" 
		                    unitType="myUnitType:massPerTime">
		                    <unit units="units:g" power="1"/>
		                    <unit units="siUnits:s" power="-1"/>
		                  </unit></h:pre>This defines a new unit (g.s-1) which is composed from two 
		                existing units (units:g and siUnits:s) to create a new unit. The
		                conversion to SI is computed from the two child units and may be 
		                added as a 'multiplierToSI' attribute. Only siUnits or units with
		                'multiplierToSI' can be used as child units; 'constantToSI cannot
		                be used yet. If the new unit points to a unitType then the dimension
		                can be checked. Thus if the published dimension of massPerTime does not
		                agree with mass.length-1 an error is throwable.
		                Alternatively a new unitType can be added as a child.</h:li>
  </h:ul>
  <h:p>The relationship of a unit to its SI parent is potentially complex and 
                inconsistencies may arise. The following are available:
    <h:ul>
      <h:li>parentSI. This points to the ID of a parent SI unit. If this ID is the 
                same as the current unit the implication is that this is an SI unit.</h:li>
      <h:li>isSI. a boolean indicating whether the current unit is SI.</h:li>
      <h:li>multiplierToSI and constantToSI. If these are 1.0 and 0.0 (or missing)
                the implication is that this unit is SI. However this is fragile as units can 
                be defined without these attributes and a unit could coincidentally have 
                no numeric differences but not be an SI unit.</h:li>

Attributes
QName Type Fixed Default Use Annotation
convention refType optional
<h:div class="summary">A reference to a convention.</h:div>
<h:div class="description">There is no controlled vocabulary for conventions, but the author must ensure that the semantics are openly available and that there are mechanisms for implementation. The convention is inherited by all the subelements, 
so that a convention for
  <h:tt>molecule</h:tt>would by default extend to its
  <h:tt>bond</h:tt>and
  <h:tt>atom</h:tt>children. This can be overwritten
    if necessary by an explicit
  <h:tt>convention</h:tt>.
  <h:p>It may be useful to create conventions with namespaces (e.g.
    <h:tt>iupac:name</h:tt>).
    Use of
    <h:tt>convention</h:tt>will normally require non-STMML semantics, and should be used with
    caution. We would expect that conventions prefixed with "ISO" would be useful,
    such as ISO8601 for dateTimes.</h:p>
  <h:p>There is no default, but the conventions of STMML or the related language (e.g. CML) will be assumed.</h:p>
</h:div>
<h:div class="example" id="ex" href="convGroup1.xml"/>
dictRef namespaceRefType optional
<h:div class="summary">A reference to a dictionary entry.</h:div>
<h:div class="description">Elements in data instances such as _scalar_ may have a
  <h:tt>dictRef</h:tt>attribute to point to an entry in a dictionary. To avoid excessive use of (mutable) filenames and URIs we recommend a namespace prefix, mapped to a namespace URI in the normal manner. In this case, of course, the namespace URI must point to a real XML document containing _entry_ elements and validated against STMML Schema.
  <h:p>Where there is concern about the dictionary becoming separated from the document the dictionary entries can be physically included as part of the data instance and the normal XPointer addressing mechanism can be used.</h:p>
  <h:p>This attribute can also be used on _dictionary_ elements to define the namespace prefix</h:p>
</h:div>
<h:div class="example" href="dictRefGroup1.xml"/>

from refType optional
<h:div class="summary">The base of one or more links.</h:div>
<h:div class="description">On link elements the value is the single id of an element within the document or context specified in map@fromRef attributes. It must identify the element uniquely. The reserved value 'null' implies that no mapping has been provided for the object(s) in the 'to' attribute. This implies no semantics but may be used by software to keep count of which elements have been mapped. For multiple targets use 'fromSet'.</h:div>
<h:div class="curation">2005-06-18: updated docs</h:div>
fromContext idType optional
<h:div class="summary">The context for the 'from' links in a map.</h:div>
<h:div class="description">
  <h:p>A reference to the unique 'id' attribute of an element defining the context for links in a map. This may be required when id attributes may not be unique within a document. The id should either reference an element uniquely or should be taken as the first ancestor (of the map) with such an id.</h:p>
  <h:p>This is fairly horrid but may be required when documents are assembled without establishing unique ids (e.g. concatenation of files). As an example a map referencing linked atoms in two molecules might use the containing 'reaction' element as its uniquifying context.</h:p>
</h:div>
<h:div class="curation">2005-06-18: created</h:div>
fromSet idArrayType optional
<h:div class="summary">A set of ids representing the base of a link.</h:div>
<h:div class="description">
  <h:p>For a partial mapping where a number of 'from' elements are known to link to a number of 'to' elements it can be useful to aggregate these into a single attribute value. The primary use is to assert that n links exist between a set of n 'from' elements and n 'to' elements but that the precise links are unknown. The semantics of the reference are the same as for 'from' and all the elements must be of the same type (which can be specified with 'fromType' either on the link or the containing map). No order information is implied. In general there will be the same number of idRefs in the 'toSet' and all implicit links will share the same attributes (e.g. 'role'). In many cases the sets will be later split into discrete links thorugh further calculation or experiment (e.g. peak assignment). Sets should never be used as a lazy or concise alternative where the all the links are explicitly known.</h:p>
</h:div>
<h:div class="curation">2005-06-18: created</h:div>
fromType xmlElementType optional
<h:div class="summary">The type of the base of a link.</h:div>
<h:div class="description">
  <h:p>The local tagname of the referenced element (e.g. 'molecule' or 'peakGroup'). This acts as a partial check on the integrity of the link. Software can assume that the referenced element is of a given tytpe and can create an object supporting that type.</h:p>
  <h:p>This attribute can be attached to the 'map' attribute and requires all contained links to be of this type. This can be overridden by a 'toType' attribute on indivdual links, but it may also be useful to split the map into maps od different link types.</h:p>
</h:div>
<h:div class="curation">2005-06-18: created</h:div>
href xsd:anyURI optional
<h:div class="summary">address of a resource.</h:div>
<h:div class="description">Links to another element in the same or other file. For dictionary/@dictRef requires the prefix and the physical URI 
            address to be contained within the same file. We can anticipate that
            better mechanisms will arise - perhaps through XMLCatalogs.
            At least it works at present.</h:div>
id idType optional
<h:div class="summary">A unique ID for an element.</h:div>
<h:div class="description">Id is used for machine identification of elements and
                in general should not have application semantics. It is similar to the XML ID type
                as containing only alphanumerics, '_', ',' and '-' and and must start with an
                alphabetic character. Ids are case sensitive. Ids should be unique within local scope,
                thus all atoms within a molecule should have unique ids, but separated molecules within a 
                document (such as a published article) might have identical ids. Software
                should be able to search local scope (e.g. all atoms within a molecule). 
                However this is under constant review.</h:div>
linkType linkTypeType optional
<h:div class="summary">The type of the link.</h:div>
ref refType optional
<h:div class="summary">A reference to an element of given type.</h:div>
<h:div class="description">
  <h:tt>ref</h:tt>modifies an element into a reference to an existing element of that type within the document. This is similar to a pointer and it can be thought of a strongly typed hyperlink. It may also be used for "subclassing" or "overriding" elements.
  <br xmlns=""/>When referring to an element most of the "data" such as attribute values and element content will be on the full instantiated element.  Therefore ref (and possibly id) will normally be the only attributes on the pointing element. However there may be some attributes (title, count, etc.) which have useful semantics, but these are element-specific</h:div>
<h:div class="example" href="refGroup1.xml"/>
role xsd:string optional
<h:div class="summary">Role of the object.</h:div>
<h:div class="description">How the object functions or its position in the architecture. No controlled vocabulary.</h:div>

<h:div class="summary">A title on an element.</h:div>
<h:div class="description">No controlled value.</h:div>
<h:div class="example" href="title1.xml"/>
to refType optional
<h:div class="summary">The target of one or more links.</h:div>
<h:div class="summary">On link elements the value is the single id of an element within the document or context specified in map@toContext attributes. It must identify the element uniquely. The reserved value 'null' implies that no mapping has been provided for the object(s) in the 'from' attribute. This implies no semantics but may be used by software to keep count of which elements have been mapped. For multiple targets use 'toSet'.</h:div>

<h:div class="summary">A container for links</h:div>
<h:div class="description">
  <h:p>Usage is now standardized with map as the container and link as the individual links. The links are often effectively typed pointers to other parts of the document. The type can be set for all links by the 'fromType' and 'toType' attributes, either in the map, which then applied to all links by default, or in individual links, when it overrides the map setting. Since ids may not be unique within a document the refs can be given context with the 'fromRef' and 'toRef' attributes in the map element. If more than one context is used it may be better to use multiple maps. The role of map, and its relationship to RDF is still being developed.</h:p>
  <h:p>Currently (2005) map has primarily been used to map atoms between reactants and products, but we also expect shortly to extend it to peak assignments and several otherr areas. A map consists of a number of links, which can be directional, relating two elements through their ids. Reference is through the mandatory 'to' and 'from' attributes which must point to existing id attributes on elements. The type of the dereferenced element can be specified in 'toType' and 'fromType' which, while redundant, is an aid to software and acts as a check on referential type integrity.</h:p>
  <h:p>In principle any element can be linked to any other, with 1:1, 1:n, and n:m topology. We expect maps to be used for precise chemical concepts such as reactions, peak assignments, electron management, molecular superpositions, etc. and that these are supported by bespoke code. For other links, especially with complex topology, users should consider whether RDF may be more appropriate.</h:p>
  <h:p>In some cases partial mapping is known (e.g. one set of atoms maps to another set), but the precise links are unknown. (This is not the same as n:m mapping where n*m precise links would be expected). In some cases there may be objects such as atomSets or peakGroups which could be linked to support this. Alternatively the 'fromSet' and 'toSet' attributes can be used to hold a list of ids. Thus from='a1 a2' to='b3 b4' might imply that there were two precise links (either {a1=>b3, a2=>b4} or {a1=>b4, a2=>b3}). This is most likely to be used in intermediate documents where more precise semantics can be added later. The ids must all refer to elements of the same type. Note that a 'to' link referencing a single atomSet (toType='atomSet') is not the same as a 'toSet' of toType='atom' with multiple atomIds. The first would require an 'atomSet' element in the document; the second would not. The precise semantics such as the order of ids are application-dependent. If the order is known in both the toSet and fromSet then individual links should be used rather than adding the burden of deconstruction on the implementer.</h:p>

convention refType optional
<h:div class="summary">A reference to a convention.</h:div>
<h:div class="description">There is no controlled vocabulary for conventions, but the author must ensure that the semantics are openly available and that there are mechanisms for implementation. The convention is inherited by all the subelements, 
so that a convention for
  <h:tt>molecule</h:tt>would by default extend to its
  <h:tt>bond</h:tt>and
  <h:tt>atom</h:tt>children. This can be overwritten
    if necessary by an explicit
  <h:tt>convention</h:tt>.
  <h:p>It may be useful to create conventions with namespaces (e.g.
    <h:tt>iupac:name</h:tt>).
    Use of
    <h:tt>convention</h:tt>will normally require non-STMML semantics, and should be used with
    caution. We would expect that conventions prefixed with "ISO" would be useful,
    such as ISO8601 for dateTimes.</h:p>
  <h:p>There is no default, but the conventions of STMML or the related language (e.g. CML) will be assumed.</h:p>

dictRef namespaceRefType optional
<h:div class="summary">A reference to a dictionary entry.</h:div>
<h:div class="description">Elements in data instances such as _scalar_ may have a
  <h:tt>dictRef</h:tt>attribute to point to an entry in a dictionary. To avoid excessive use of (mutable) filenames and URIs we recommend a namespace prefix, mapped to a namespace URI in the normal manner. In this case, of course, the namespace URI must point to a real XML document containing _entry_ elements and validated against STMML Schema.
  <h:p>Where there is concern about the dictionary becoming separated from the document the dictionary entries can be physically included as part of the data instance and the normal XPointer addressing mechanism can be used.</h:p>
  <h:p>This attribute can also be used on _dictionary_ elements to define the namespace prefix</h:p>

  <h:p>This attribute can be attached to the 'map' attribute and requires all contained links to be of this type. This can be overridden by a 'toType' attribute on indivdual links, but it may also be useful to split the map into maps od different link types.</h:p>

<h:div class="summary">A unique ID for an element.</h:div>
<h:div class="description">Id is used for machine identification of elements and
                in general should not have application semantics. It is similar to the XML ID type

                thus all atoms within a molecule should have unique ids, but separated molecules within a 
                document (such as a published article) might have identical ids. Software
                should be able to search local scope (e.g. all atoms within a molecule). 
                However this is under constant review.</h:div>

<h:div class="description">

  <br xmlns=""/>When referring to an element most of the "data" such as attribute values and element content will be on the full instantiated element.  Therefore ref (and possibly id) will normally be the only attributes on the pointing element.

<h:div class="description">Primarily to record couplings and other fine

<h:div class="summary">A reference to a list of bonds.</h:div>
<h:div class="description">Used by electrons, bondSets, etc.</h:div>
convention refType optional
<h:div class="summary">A reference to a convention.</h:div>
<h:div class="description">There is no controlled vocabulary for conventions, but the author must ensure that the semantics are openly available and that there are mechanisms for implementation. The convention is inherited by all the subelements, 
so that a convention for
  <h:tt>molecule</h:tt>would by default extend to its
  <h:tt>bond</h:tt>and
  <h:tt>atom</h:tt>children. This can be overwritten
    if necessary by an explicit
  <h:tt>convention</h:tt>.
  <h:p>It may be useful to create conventions with namespaces (e.g.
    <h:tt>iupac:name</h:tt>).
    Use of
    <h:tt>convention</h:tt>will normally require non-STMML semantics, and should be used with
    caution. We would expect that conventions prefixed with "ISO" would be useful,
    such as ISO8601 for dateTimes.</h:p>
  <h:p>There is no default, but the conventions of STMML or the related language (e.g. CML) will be assumed.</h:p>
</h:div>
<h:div class="example" id="ex" href="convGroup1.xml"/>
dictRef namespaceRefType optional
<h:div class="summary">A reference to a dictionary entry.</h:div>
<h:div class="description">Elements in data instances such as _scalar_ may have a
  <h:tt>dictRef</h:tt>attribute to point to an entry in a dictionary. To avoid excessive use of (mutable) filenames and URIs we recommend a namespace prefix, mapped to a namespace URI in the normal manner. In this case, of course, the namespace URI must point to a real XML document containing _entry_ elements and validated against STMML Schema.
  <h:p>Where there is concern about the dictionary becoming separated from the document the dictionary entries can be physically included as part of the data instance and the normal XPointer addressing mechanism can be used.</h:p>
  <h:p>This attribute can also be used on _dictionary_ elements to define the namespace prefix</h:p>
</h:div>
<h:div class="example" href="dictRefGroup1.xml"/>

id idType optional
<h:div class="summary">A unique ID for an element.</h:div>
<h:div class="description">Id is used for machine identification of elements and
                in general should not have application semantics. It is similar to the XML ID type
                as containing only alphanumerics, '_', ',' and '-' and and must start with an
                alphabetic character. Ids are case sensitive. Ids should be unique within local scope,
                thus all atoms within a molecule should have unique ids, but separated molecules within a 
                document (such as a published article) might have identical ids. Software
                should be able to search local scope (e.g. all atoms within a molecule). 
                However this is under constant review.</h:div>
peakMultiplicity peakMultiplicityType optional
<h:div class="summary">Multiplicity of a peak.</h:div>
<h:div class="description">Uses a semi-controlled vocabulary.</h:div>
peakShape peakShapeType optional
<h:div class="summary">Shape of a peak.</h:div>
<h:div class="description">Semi-controlled vocabulary such as broad or sharp.</h:div>
ref refType optional
<h:div class="summary">A reference to an element of given type.</h:div>
<h:div class="description">
  <h:tt>ref</h:tt>modifies an element into a reference to an existing element of that type within the document. This is similar to a pointer and it can be thought of a strongly typed hyperlink. It may also be used for "subclassing" or "overriding" elements.
  <br xmlns=""/>When referring to an element most of the "data" such as attribute values and element content will be on the full instantiated element.  Therefore ref (and possibly id) will normally be the only attributes on the pointing element. However there may be some attributes (title, count, etc.) which have useful semantics, but these are element-specific</h:div>
<h:div class="example" href="refGroup1.xml"/>
title xsd:string optional
<h:div class="summary">A title on an element.</h:div>
<h:div class="description">No controlled value.</h:div>
<h:div class="example" href="title1.xml"/>
type peakStructureTypeType optional
<h:div class="summary">Type of this structure.</h:div>
<h:div class="description">Semi-controlled vocabulary such as coupling 
                or splitting.</h:div>
units unitsType optional
<h:div class="summary">Scientific units on an element.</h:div>
<h:div class="description">These must be taken from a dictionary 
                of units. There should be some mechanism for validating the type

                thus all atoms within a molecule should have unique ids, but separated molecules within a 
                document (such as a published article) might have identical ids. Software

convention refType optional
<h:div class="summary">A reference to a convention.</h:div>
<h:div class="description">There is no controlled vocabulary for conventions, but the author must ensure that the semantics are openly available and that there are mechanisms for implementation. The convention is inherited by all the subelements, 
so that a convention for

  <h:tt>convention</h:tt>.
  <h:p>It may be useful to create conventions with namespaces (e.g.

    Use of

In this case, of course, the namespace URI must point to a real XML document containing _entry_ elements and validated against STMML Schema.
  <h:p>Where there is concern about the dictionary becoming separated from the document the dictionary entries can be physically included as part of the data instance and the normal XPointer addressing mechanism can be used.</h:p>

<h:div class="summary">A reference to a map providing mappings between electrons</h:div>
<h:div class="description">The map will normally be contained within the same document and referenced by its ID. It will contain a list of links with from and to attributes linking electrons. The topology of the linking is defined by the application - it could be reactant/product mapping, etc. The reserved phrase "USE_IDS" assume that the sets of electrons are of equal size and have 1:1 mapping between each id.

<h:div class="summary">Format of the reaction component.</h:div>
<h:div class="description">Indicates how the components of reactionScheme, reactionStepList, etc. should be processed. No controlled vocabulary.

Note that the reaction can be interpreted without reference to the format, which is primarily a processing instruction.</h:div>

<h:div class="summary">A unique ID for an element.</h:div>
<h:div class="description">Id is used for machine identification of elements and

                as containing only alphanumerics, '_', ',' and '-' and and must start with an
                alphabetic character. Ids are case sensitive. Ids should be unique within local scope,
                thus all atoms within a molecule should have unique ids, but separated molecules within a 
                document (such as a published article) might have identical ids. Software
                should be able to search local scope (e.g. all atoms within a molecule). 
                However this is under constant review.</h:div>

<h:div class="description">
  <h:tt>ref</h:tt>modifies an element into a reference to an existing element of that type within the document. This is similar to a pointer and it can be thought of a strongly typed hyperlink. It may also be used for "subclassing" or "overriding" elements.
  <br xmlns=""/>When referring to an element most of the "data" such as attribute values and element content will be on the full instantiated element.  Therefore ref (and possibly id) will normally be the only attributes on the pointing element.

<h:div class="summary">A container for one or more related reactionSteps.</h:div>
<h:div class="description">
  <h:p>
    <h:tt>reactionStepList</h:tt>is always contained within reactionScheme and is designed to manage "sub-reactions" which have close relationships. These will often involve reactions which, taken together, describe a higher level reaction or reaction type. Examples are:
    <h:ul>
      <h:li>biochemical pathways</h:li>
      <h:li>synthetic reaction schemes</h:li>
      <h:li>multi-step reactions</h:li>
      <h:li>parallel and/or coupled reactions</h:li>
    </h:ul>.
          A reactionStepList contains reactionSteps (each of which contains reactions and/or reactionSchemes (e.g. where part of the process is known in greater detail)). It may not directly contain child reactionStepLists.</h:p>
  <h:p>The child reactionSteps can have attributes such as yield and ratio which describe the relationship of the component steps.</h:p>
  <h:p>Guidance on use:
    <h:ul>
      <h:li>reactionScheme describes a complex of reactions with metadata, one (or more) overall reactions and a reactionStepList with the overall component reactions.</h:li>
      <h:li>reactionStepList aggregates and structures the individual subreactions.</h:li>

  <h:p>A reference to an existing element can be used to supplement values such as coordinates.  The
