I don't think it should really have the DTD built-in because that would
prevent using different DTDs to describe HTML.  We will assuredly have
multiple DTDs in common use soon(ish).  It might make sense to be able to
pre-compile a DTD for efficiency, though.

I'd be happy with a production version in Perl5, too.  I rarely do
validation on the fly, so I don't need that extra 30-50% that C might give.

Hmm, as a thought, I might really appreciate a Perl version, because I could
see hooking into such a parser to provide arbitrary functionality.  As long
as I'm parsing my HTML documents, I might as well update the databases of
LINK tags, run a link validator, and so forth.  I'd rather write the code
for these add-ons in Perl.  Heh, as long as you're using Perl 5, why not
just code up only the critical parts in C using Perl 5's extensibility
mechanisms?
