I'm not sure whether requiring URIs as configuration keys is such a
smart idea, anyway. SAX uses that approach, DOM uses simple strings
(like 'core' or 'mutationevents'). Works equally well, IMO. Even for
SAX, most Python users probably don't write 

  p.setFeature("http://xml.org/sax/features/namespaces", 1)

but

  from xml.sax.handler import feature_namespaces
  ...
  p.setFeature(feature_namespaces, 1)
