            The target of the ref attribute must exist. The test for validity will normally 
            occur in the element's _appinfo_. Any DOM Node created from this element will 
            normally be a reference to another Node, so that if the target node is modified 
            a the dereferenced content is modified. At present there are no deep copy 
            semantics hardcoded into the schema.</h:div>
            <h:div class="description" xmlns:h="http://www.w3.org/1999/xhtml">The semantic of reference are normally identical to 
            an idType (e.g. "a123b"). Howevere there are some cases where compound references
            are required, such as "a123b:pq456". It is likely that this will be superseded at
            by RDF or Xpointer, but as long as we have non-uniqueIds this is a problem</h:div>
