Just for reference.. (please correct me if I'm wrong)

The { string, Name } model of namespaces is what 
XPath specification uses.  The namespace spec uses
a 4-tuple { type, string, parent-local, local }
where type is "element" or "global-attribute" 
or "per-element-attribute" and where parent-local
is null except for the "per-element-attribute",
in which case, it is the parent element's local.
