Since you mention it, let me give this pointer:
http://yquem.inria.fr/~frisch/xml-schema/

The module Schema_loader is the most relevant one. It is an XML Schema
loader, written in the OCaml+CDuce extension. This is work in progress,
but you can already see how CDuce patterns help to inspect XML data.
