There's a problem with this. The Nodes object returned by query can't 
contain a non-Node (or rather it can, but the call to get() for that 
node would throw a ClassCastException). Options

1. Just make XPathNamespaceNode a subclass of Node.
2. Wrap the namespace node in something that can be returned, like an 
Element in a particular namespace.
3. Just make the query method return a List instead of a Nodes
4. Add an additional query method, probably in a separate package, that 
does return a List.

I don't like any of these solutions. 2 and 4, however, seem the least ugly.
