   <!-- For PRE-VALIDATING the validation (House Rules) file set -->

   <!--This XProc echoes Schematron validation findings (failed assertions and successful reports)
       to the console - *without erroring*
       
       Accordingly it does not defend against errors in next steps, for example if resources are not found.
       
       Hence under CI/CD we are now using REPO-FILESET-CHECK.xpl -
         
       Use this pipeline for a hand pre-check
   -->

   <!-- Schematron will alert if either of these point to resources unavailable - this gives early
        diagnosis of one of the most common reasons for failure in the next step -->
