Hm, seems like that is operating at the next level down; it starts with
XmlTableSetNamespace's response to a null "name" argument, whereas what
I'm on about is what happens before we get to that function.

There's quite a bit I don't like about that patch now that I look at it
:-(, but I don't think it's relevant to this thread.
