As a programmer, I agree with you. Now, imagine a user typing an XPath 
expression after having selected a node or, in a script written in XML, as the 
value of an attribute of a node. How would you expect the guy to understand 
you do not automatically recognize the namespace prefix defined 2 nodes higher 
up in the hierarchy ?
Maybe this is a very specific use-case but it is truly a case where one needs 
automatic namespace resolution. Hence the NamespaceContext implementation.
And adding to the XPath object all the namespaces declared from the node up to 
the document root is quite cumbersome.

No, I'm fine with namespaces. I just need to provide a user-friendly way to 
deal with them.
