ISO Schematron has a little language called SVRL (Schematron Validation
Reporting Language). It basically is a list of <failed-assert>
elements. (It is being used for the test suite due to be finished this
week. )
It was provided by user request. One of the earliest implementations of
Schematron, ZVON Schematron, produced an output document, and so was
convenient for subsequent processing. My Screamathon Torture Test used a
similar approach as well.
Defining the outcomes of validation as an XML document is very good,
because it maintains an XML-in/XML-out workflow, and presumably is less
non-disruptive than a non-XML "PSVI" API approach.
