| Are there any examples of XML documents that use IDREF? 

I've got one at

<URL:http://birk105.studby.uio.no/www_work/xml/sgmlglos.xml>
<URL:http://birk105.studby.uio.no/www_work/xml/glos_xml.dtd>

Actually, that's one DTD it would be very nice to have for testing
purposes. Is it available anywhere? (Please?)

In my experience ID/IDREF is very nice for simple cross-references
inside a document, since they're so simple to use. (The error handling
need not be Draconian.  nsgmls-like behaviour where the reporting can
be turned off is IMHO sensible for this, since there may be invalid
references while the document is being written.)

| IDREFs are concise and simple to implement(?). 

Compared to XLL, yes, but they do require a parser that reads the
DTD. I've not added them to my own parser yet, but they won't require
much work (unless there are hidden surprises, of course).
