In the long run[XML Packaging], yes.  For XML Schemas, no.  Catalogs
are a minefield, I don't want to go there.

Um, I'm lost.  We're discussing a case where an instance uses various
namespaces, schema documents for which I have local copies of.  What
it _means_ to have a schema document for a namespace is to have a
schema document whose 'targetNamespace' attribute is the name of that
namespace.  So when I provide those local copies to the
schema-validation process, I've essentially provided both LHS
(targetNamespace) and RHS (local filename for schema document)
for a catalog.
