It would require a change to attributes as well, which might be stranger
given the Namespace rec's way of leaving attributes out of the default
namespace and all.
We also need some way to identify to a DTD processor which namespace URI is
associated with which prefix.

That new category needs to be defined someplace, if it's to really exist,
and I think we've seen enough discussion on this list to know that it's not
going to be supremely easy.

That definitely helps! Now we just just parsers that rely on a good open
DTD processor that's loosely coupled rather than tightly bound. (I'm
working on one, but have zero time. I shouldn't even be talking here!)
