Is it possible to add modes for relax-ng and relax-ng compact now that nxml is in?

[Eric Lilja]

Hi, I'm running emacs 23.0.50.1 which I build often on windows and 
sometimes I also build 23.0.60.* under GNU/linux (fedora). I was very 
pleased when nxml was added to emacs (but only to 23.0.50.1, or? I can't 
wait for the unicode-branch to be merged....) and now I've started to 
work with it. I particularly like the fact that I can write relax-ng 
compact schemas and validate my xml-files against those schemas. My 
simple question is that if it's possible to add a mode for relax-ng 
compact (and relax-ng)? It would fit very well with nxml and make 
editing schema files much more attractive. I'm trying to keep my 
dependencies on third-party code to a minimum, that's why I'm suggesting 
this here.
