There's another C++ implementation: QtXmlPatterns, although we(Trolltech) 
haven't announced on these XML lists yet.

http://doc.trolltech.com/4.4/qtxmlpatterns.html

I believe it's fairly similar to XQilla in-scope(haven't looked into Zorba). 
I'd say the advantages of QtXmlPatterns in the 4.4 release is:

* Portability: windows, OS X, Linux, Windows CE, Unix, etc; most platforms 
that the Qt framework runs on
* Easy to use; ok documentation, simple value based classes
* Open source, but commercially backed
* Suitable for easy integration with other C++ code. For instance, one of the 
examples runs an XQuery on top of the widget hierarchy in the current running 
program.

However, QtXmlPatterns doesn't sport schema validation and it doesn't have a 
database backend.
