OK. I'll forward your scenario to the Orbeon guys who are best placed to
elegantly implement it with XPL.

What did surprise me a lot with this scenario is that it isn't pure
validation but requires a result that is a transformed infoset. To me,
that looks like something which is useful but against the general
principles of DSDL which focuses on pure validation. I thin that it goes
beyond what we've called Validation Management so far and is more a
scenario for a general purpose pipeline language with validation
support.

PS: Even if that's probably useless after the decision you've taken in
Washington, I'll try to finalise what I had in mind for Validation
Management.
