Yes, but that's not enough.  There should only be one instance of any
given Namespace prefix/uri pair.  Just making it Serializable would
allow for there to be multiple instances.  That requires custom hooks in
the serialization process that make use of Namespace.getNamespace() to
ensure uniqueness; we may even need to make the class Externalizable, I
haven't thought it thru.  Fixing this is one of the items listed in
TODO.txt.  If you want to investigate and make a suggested fix, feel
free!

Cool, just fixed in CVS.
