Indeed.  Actually I'd ideally like to make it writable and add a
void* userdata field (which I'd use to store a function that'll
be called from SAX [start|end]Element handlers).  But I thought
that making it non-const would probably not be acceptable.

Yes.  Or, equivalently, XHTML 1.0.  It's basically just extending
what you've done.

Indeed.  Yes, it would benefit from that info.  The reason I don't suggest
it is that I haven't implemented it in this form, but it should be
straightforward.  Also there's the issue that you can't do meaningful
repair of missing attributes without human intervention.

If so I've overlooked it.  But I've done most of the hard work for
libhtnorm - and am now reusing that.

OK, will do.

Any recent changes to htmlParser?  Should I be sure to patch
against current CVS, or will a recent-ish 2.4.x release suffice?
