Well, if you manage to change this *quickly*, you have my support :-)

Anything that works is fine with me - it does not need to be elegant,
it must be consistent, and it must be available RSN. Why don't you
just post a snapshot patch now?

Sounds good. The next question then is: which of those should be
invoked by the parsers, under what circumstances?

I can see two alternatives:
a) depending on some configuration setting, the parser invokes only
   one set.
b) the parser always invokes *NS. The base class implements that as

   def startElementNS(self, name, qname, attrs):
     return self.startElement(qname, attrs)

Which one is it, or is it something else?
