Is it more of a conceptual challenge to add an attribute declaration to the internal subset than it is to add a global namespace
declaration to the internal subset? The only difference is that the attribute declaration rquires that one must determine the
"root" element. I would have thought one needed to make that decision in order to encode the internal subset.
