WARNING : when working with the current code in CVS, you'll have to change
all the code accessing attributes in your code :
elt.getAttributeNS('','foo')
becomes
elt.getAttributeNS(None,'foo')

This includes lots of code in xml.xslt; I'll try to commit the changes in
PyXML's repository tonight or tomorrow morning since I have to leave early
today, and I'll submit a patch for 4Suite's at the same time.

Would adding an "EMPTY_NAMESPACE = None" to xml/dom/__init__.py, just
after the definitions of XML_NAMESPACE and XMLNS_NAMESPACE be considered
to be a good idea?
