[XML-SIG] sgmlop and xmllib.py compatibility

[A.M. Kuchling]

I'm finally getting back to working on the XML code.  A while back
Sjoerd checked in various fixes to the xmllib.py in the Python 1.5 CVS
tree; these changes result in a divergence between FastXMLParser
(which uses sgmlop) and the regular XMLParser in xmllib.py.  Looking
at it, I'm wondering why FastXMLParser isn't a subclass of the
original XML parser that overrides certain methods, but instead copies
the methods of xmllib.XMLParser.  Subclassing would seem to make
keeping the two compatible slightly easier.
	
	Any thoughts?  Fredrik?
