Oh, I think because DTD syntax is similar to, but not compatible with, 
SGML.

Ok, I accept that.  My point is that if you implement an XML parser, this 
is all you need to *parse* XMLSchema.  You have to write an additional 
parser if you want to parse DTD.  Similarly, to support SGML you have to 
write code that parses SGML syntax and additional code specifically to 
handle DTD syntax.

That would be nifty-keen.  I'm procrastinating working on my parser.  If 
you keep me in the loop, I'll be happy to replace REXML's DTD parsing code 
with your code.
