Looking at DAFFODIL-2482 that came up due to a gap that's blocking integration of the schematron validation functionality into some workflows that require the full SVRL output, not just the pass/fail status.
So what needs to happen here is the SVRL that we currently just parse for errors and discard needs to be output in a predictable way. I've tried a couple things intent on minimizing the footprint of the impl but coming up empty mainly due to violating the reusable validator principle. So another unminimized approach would be to provide an additional stream to all validators for raw output to be written, the implementation of that stream is determined by configuration from the DataProcessor. The new output stream is passed at validation-time, which requires changing the signature of the validate call to accept this output stream in addition to the existing input stream (or we could add another interface, but I'm not convinced of the usefulness of that currently). Looking for some thoughts on this approach. [1] https://issues.apache.org/jira/browse/DAFFODIL-2482
