Yes, David, but you're taking me somewhat too literally here (this is what I
meant about being "insufficiently imaginative").  If I rephrased what I
wrote as:

"It is not too hard to evolve the concept of today's DTD validation to
support two part locally scoped names (including the default prefix)."

Would you still disagree with it?

I believe this can be done -- it would obviously not be the validation as
specified in XML 1.0, but a sensible evolution of the same.  However, as I
also said in my post, it would be essentially worthless, because it would
encourage placing the prefix in the DTDs.  I believe even this can be dealt
with, but I'd rather spend the efforts on a new schema language, than
patching DTDs.
