Not that I know of.  Rather than specify and additional xml file, why
don't you use a schema (xsd or relax ng) instead.  You could then query
that as xml and get the information you need (whilst of course still
validating the file).  

There is an app called trang
(http://www.thaiopensource.com/relaxng/trang.html) by James Clark that
can translate between dtd, xsd and relax ng if you didn't fancy doing it
by hand.
