Fine. In reality, the DTD issue may be more of a DTD processor value issue
rather than an XML spec issue per se. A "namespace conformant" DTD validator
would validate based on expanded names rather than prefixed names. This
could be handled by a change to the "Element Valid" validity constraint (not
really a big deal - IHMO).

"Validity Constraint: Element Valid
An element is valid if there is a declaration matching elementdecl where the
Name [jb insert QName] matches the element type, and one of the following
holds:
..."

This would make such a document "Namespace Valid" rather than "XML 1.0
Valid" -- perhaps this is a new category.

Now that we have a good open source DTD processor...
