Me too.

I think it's a matter of very detailed use of English. :)  I view it as
a utility.  But it doesn't matter.

No, the proper term really is canonicalization.  I agree, the name is
somewhat cute, but within the community C14N is as well-known as I18N.

How about
	from xml.dom.ext import Canonicalize
and in ext/__init__.py I add
	from c14n import Canonicalize

So the filename is c14n.py, but the exported name is more use-friendly.
