Update of /cvsroot/python/python/dist/src/Lib/xml/dom
In directory sc8-pr-cvs1:/tmp/cvs-serv19715

Modified Files:
	domreg.py 
Log Message:
Merge with PyXML 1.3:
Add support for the DOM Level 3 (draft) DOMImplementationSource interface
to the xml.dom and xml.dom.minidom modules.  Note API issue: the draft spec
says to return null when there is no suitable implementation, while the
Python getDOMImplementation() function raises ImportError (minor).
