I heard someone mention (and I can't remember where or when... but it's
not my original idea) the idea of having standards for a validation
warning/error format.  When validation was done on an instance, it would
result in a document snippet that represented the results of that pass
of validation.  Snippets could be concatenated from several validation
steps, and the result would be a coherent report on the validity of the
instance.

Is something along those lines what you mean when you say "getting them
[schematron and XSD] to work together cleanly"?
