You know it really weird how mnay people report problems without
mentioning what implementation they're using.  Look: the XQuery
specification isn't even done, and the different implementations
have different status - and bugs.

'except' only removes the actual nodes in the seconds xpressions,
based on node identity.  It doesn't check for children.

Also $n//* will give you lots of duplication.

I think you'll have to write a recursive tranformer.
See appendix G.4 in the latest (Octover 2004) draft.
