  I like this idea; very Pythonic!  The exceptions and .code values
could live in xml/dom/__init__.py (or at least be imported there so
the values are used from xml.dom, instead of from individual DOM
implementations.
  I'd also like to see the .nodeType values defined this way, and
  shared by the implementations.

  I don't know about the i18n issues; I'll bow to your superior
expertise in this area.
