I suspect if you take the problem the other way round, and try to prove
incorrectness, you will make a lot more progress. I would think there are a
large number of cases where, given a schema to which the source document
must conform, and a stylesheet, I can prove quite easily that the result
will NOT always conform to a given result schema. That sounds like a
worthwhile thing to do.
