In the XML encoding 4.3.4
(<a class="moz-txt-link-freetext" href="http://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#DEFAndUSEAttributeSyntax">http://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#DEFAndUSEAttributeSyntax</a>),
the first paragraph discusses DEF and USE structures. It states
"[t]he same name-construction conventions regarding legal
character combinations apply" where DEF is of XML type 'ID' and
USE is of XML type 'IDREF'. <br>
<br>
If you trace through the XML definitions for ID, XML (as best as I
can tell) allows a dash, except as a first character. I ended up
at <a class="moz-txt-link-freetext" href="https://www.w3.org/TR/REC-xml/#NT-Name">https://www.w3.org/TR/REC-xml/#NT-Name</a> where the definition of
'Name' is made.<br>
<br>
I am confused about the definition of USE. The 19776-1 document
states that it is of type XML IDREF. IDREFs appear to be only
usable in Document Type Definition as part of the ATTLIST
declaration (see <a class="moz-txt-link-freetext" href="https://www.w3.org/TR/REC-xml/">https://www.w3.org/TR/REC-xml/</a> or
<a class="moz-txt-link-freetext" href="http://xmlwriter.net/xml_guide/attlist_declaration.shtml">http://xmlwriter.net/xml_guide/attlist_declaration.shtml</a>). I am
not sure if 19776-1 is extending the definition to a new use or it
is using the term incorrectly.<br>
