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.
