<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 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 doc containing _entry_ elements and validated against STMML Schema.
<h:p>Where there is concern about the dictionary becoming separated from the doc 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="summary">The namespacePrefix for a data item.</h:div>
<h:div class="description">The dictionaryPrefix is associated with elements such as dictionaries and units and allows them to be referenced namespaces. The dictionaryPrefix is normally unbound but it may be necessary to hardcode them occasionally. Thus if a value is fixed (e.g. "xsd:double") the prefix must be identified and fixed.</h:div>

<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>

<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 doc (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>
