Just a note...

There's been quite the discussion of IDs-without-DTDs/Schemas over on
XML-DEV lately.  I think Leigh Dodds has recapped at xml.com, also.

Basically:  It's not a trivial thing, to find IDs without a document
descriptor of some sort.  Folks are working on a standard way to deal 
with it, but in light of SOAP (which requires no DTD, and disallows
PIs, etc), and other formats, it becomes a Hard Problem rather quickly.
