[regrep] DTD Synatx for FilterQuery

[Len Gallagher <LGallagher@nist.gov>]

Registry TC,

Attached is a text file that extracts and collects together all of the XML 
Element definitions from the FilterQuery proposal distributed to this list 
on Oct 12:

   http://lists.oasis-open.org/archives/regrep/200110/msg00038.html
   http://lists.oasis-open.org/archives/regrep/200110/pdf00002.pdf

I vaguely remember distributing this text file to the "query" team earlier 
but cannot find it in the archive in order to reference it. So here it is 
again for the whole TC. When combined with the XML definitions for Clause, 
and all ebRIM classes, it validates as a well-formed DTD.
