FilterQuery XML text

[Len Gallagher <LGallagher@nist.gov>]

Query team,

Attached is a text document that gives the XML Element definitions for the 
FilterQuery revision that I distributed to this list last week. i.e.

     http://lists.oasis-open.org/archives/regrep-query/200109/msg00073.html

The source had a couple of typos (e.g. missing parentheses) that I've since 
corrected.

The attached file validates OK according to the Turbo XML product from Tibco.

As I've said previously, I have no objection to translating these element 
definitions into XML Schema, I'm just not the right person to do it. I 
don't see anything inherently incorrect with having the Query specification 
in terms of a DTD and the formal XML specification for conformance testing 
as XML Schema.
