I think that requiring weak references is unreasonable for a cross-platform
API.

I agree that this would be a useful property, and I suggest that it
be exposed as a standard SAX2 feature, perhaps named "names-interned-namespaces".

Unless there is a mechanism for recovering the namespace name from the
name, this will not work well, as application behavior will depend on
particular namespace names.
