Jesper, I think you will find most support for validation is limited
to DTD's - AFAIK, Sean McGrath's book XML processing with Python,
provides one utility in particular, XMLV, that will validate an XML
document against a DTD but NOT a xml schema.  If the parser cannot
locate the DTD, it reverts to a non-validating version (essentially
the equivalent of his XMLN tool - a non-validating parser).  Sean's
book does not address validating documents against XML schemas at all
- pretty understandable given the state of the schema standard at the
time it was published.  Sean's book does have a number of very useful
tips nevertheless.

I presume you've checked out Fourthought's FourSuite product.  While
it does have tools for XSLT, XPATH, RDF, SAX and DOM -  I'm pretty
sure it also doesn't provide tools to validate documents against a
schema - but I would definitely check that site out first to be
certain.

You might also want to check out sourceforge - I seem to recall a
recent post about a couple projects to build wrappers to make Apache's
xerces and xalan tools available to python - I can't speak to that
effort or whether it addresses your specific question.
