If you are talking about validity issues only (*not* well-formedness)
then you might find my new tree-pattern validator "The Schematron"
useful.

 If you use "assert" elements you can get error reports when validity
conditions are not met (the validity conditions use XPath expressions.)
If you use "report" elements, you can get messages when certain patterns
are found, which can help you figure out what kind of structures are in
your documents.

The Schematron website is at.
http://www.ascc.net/xml/resource/schematron/schematron.html

You can also use it for string-testing of the values of elements and
attributes, and many things that DTDs cannot give.
