Review Comment:
   Will getNamespaceUri return an empty string (i,.e. not null) when there is 
no namespace?

Review Comment:
   There's no need to do all this parsing. The namespace URI should be a fixed, 
known string and that remains true in future versions. We should not change the 
namespace URI in new versions.
