People are fumbling around because they're mixing up validation and
processing.
If we're talking about DTD validation (as the original message was),
then this camp is correct: as defined in the XML 1.0 REC, DTD
validation is concerned entirely with surface names and can have no
knowledge of the underlying namespace URI.
Namespace-aware XML *processing*, on the other hand, must ignore the
prefix and work with the namespace URI, as explained in the Namespaces
WD.
When the XML Schema WG finishes its work, we should have a standard
way to do namespace-aware validation; in the mean time, XML 1.0 DTDs
is all we have.
All the best,
David
