Add W3C XML Schema validation support

This was done by Tobias Koenig, as part of an internship at Trolltech/Qt
Software, started at Wed Oct 1 18:32:43 2008 +0200, and the last commit being
part of this commit dating Tue Feb 24 11:03:36 2009 +0100. This is work
consisting of about 650 commits squashed into one, where the first commit was
