Yep, this is a start, but the implementation doesn't seem quite complete
to me. It could work well with DTDs consisting only of a single file,
but the current trend with DTDs seems to be modularization, where the
DTD is split into multiple parts. IIRC W3C encourages modularization
nowadays.
For an example, see the XHTML 1.1 DTD:
<http://www.w3.org/TR/xhtml11/xhtml11_dtd.html>

that introduces some trickyness them
i am assuming the components are listed in the main DTD
so i guess parsing the DTD would need to be done to find the
components and get them as well

Yep, something like that. I guess the DTD is parsed anyway, and maybe
making the entity resolver smart enough to retrieve the modules too
would work. OTOH, libxml and friends could provide this kind of
functionality for free...

sounds like a good plan to me
anyone want to help with making a libxml module for XEmacs ?
