There's another problem with this suggested method: there's no 
guarantee there's only one prefix for this URI. There's not even any 
guarantee there's only one prefix used on the current element. 
Providing an XPath like namespaces in scope requires using the 
prefixes to iterate rather than the URI because there's a many-to-one 
relationship between the prefixes and the URIs.

Right now my thinking is to allow an iteration across all locally 
declared namespaces (including ones implicitly declared by the 
element and its attributes)  through getNamespacePrefix(int i) and 
getNamespaceDeclarationCount(). I could shift that to namespaces in 
scope if there seemed to be a need but right now I don't see much of 
a need for that.
