I've recently tried to use XmlPatterns to validate a large XML (500MB)
against an XML schema. It ran for hours and at some point I just gave up
and aborted the program.

I tried xmllint (--schema) with the same input which ran pretty fast
(seconds).

Caveat: I am not sure if xmllint is, in what it does, really comparable
to XmlPatterns.
