Actually, it's part of what we all came up with for SAX2 last

Unfortunately, using only the NamespaceDeclHandler makes more work for
applications that care just about Namespace-qualified names, and makes
those applications less efficient (since the parser has probably
already done the work that the application will have to do over): I
agree with James and Tim that such applications will be the most
common, and we should optimize for them.

All the best,
