I'm sympathetic that we may want a setName() and setNamespace() pair of
methods to make it easier to modify all aspects of the doc
programatically.  I talked with Elliotte at the O'Reilly conference this
afternoon and he's not convinced yet.  What we need is a compelling
example where it's appropriate to change the namespace of all elts in a
document programatically.  If we have that, I think Elliotte our
strongest naysayer will be convinced.  So...  What's your use case?
