"Converting DTDs (and DTD developers) to RELAX NG schemas" paper

I've written a paper for XML 2003 on a technique for dual use of DTDs and
RNG schemas suggested by James on the nxml list
(http://groups.yahoo.com/group/emacs-nxml-mode/message/129). I've posted the
paper at http://www.snee.com/bob/temp/06-04-05.html, and would love to hear
suggestions from anyone who has a chance to read it in the next few days. 

One question I have in particular is whether "add-on schema," as I've termed
it, is the most appropriate name for a schema that specifies constraints to
be used in conjunction with a DTD, or if another term makes more sense, such
as "auxiliary schema." 

Writing this was a bit of a milestone for me: I downloaded the conference
paper DTD, converted it to RNC, and wrote the paper using Emacs and nxml
without ever looking at the DTD or RNC files. (The acronym "RNC," by the
way, has odd associations for people in the United States, because it
usually refers to the "Republican National Committee," the group that runs
George Bush's political party.)
