Actually, rather than making this method public, a nice trick might be
to return some construct that implements
javax.xml.namespace.NamespaceContext

I don't think I want to introduce an external dependency on that class since it wasn't a standard part of the JDK until 1.5, and there's probably some silly legal reason I can't ship it bundled into XOM.

I have been looking at how namespaces are handled lately. One change Wolfgang suggested (caching namespaces in a stack as the tree is traversed) sped up serialization by a few percent. There may be other improvements that can be made there, and some of these might be exposed to the public if I'm convinced they're generally useful.

Right now I'm using a map to pass these things back and forth, and I'm trying to eliminate that. However, if I made this public I'd come up with something more type-safe, probably something similar to the Elements class except it would contain Namespace objects instead of Element objects.
