The problem are prefixes, not namespaces: In the parser, null is 
returned for "no prefix" (see javadoc). In the serializer, null 
would be returned from getPrefix for "no prefix defined", and an 
empty string would be returned for namespace is default (no 
prefix in elements required). This seems a bit inconsistent, but 
it would be fine with me...
