This is a serious problem inherited from SGML. It is my opinion that
instead of namespace declarations being done through attributes they
should have been just another form of PI-based declaration. Then in
version 2.0 of XML, all declarations should have been made "localizable."
In particular, there should be a way to declare internal text entities,
unparsed entities and attribute defaults locally.
