Validating XML parsers

[Dale Strickland-Clark]

A few days ago there was a discussion about which XML parser to use with
Python.
However, the discussion didn't cover validating parsers, at least, not
w3.org XML Schemas.

I looked into all the parsers that came up in the discussion but found no
mention of w3.org schemas.

It seems there are a few DTD validating parsers but that's all.

I'm not concerned about speed so much as a reasonably sound implementation.

What's out there? Have I missed something?

Thanks.
