Validate uncaught exception for errors found in Schematron

Checked for duplicates

Yes - I've already checked

🐛 Describe the bug

When I did performed validate against the test data below with the test schemas/schematrons, validate raises an exception.

🕵️ Expected behavior

I expected validate to catch and throw a more reasonable error message (if possible).

📜 To Reproduce

./validate --schema schemas/*.xsd --schematron schemas/*.sch --target julian_dates_unit_check_VALID.xml --skip-content-validation

See test data below for the schemas and test data. Warnings are expected from the execution because the schemaLocations and schematron prolog are missing, but it should still run without exception.

⚙️ Engineering Details

Note: The rule in the schematron that Saxon doesn't like (even though I think it is valid XPath) is:

  <sch:pattern>
    <sch:rule context="sb:SB_Metadata//.[ends-with(name(),'_JD')]">
      <sch:assert test="@unit eq 'julian day'">
        <title>sb:SB_Metadata//.[ends-with(name(),'_JD')]/Rule</title>
        The attribute "<sch:value-of select="name(.)"/>" must be specified with "unit='julian day'".</sch:assert>
    </sch:rule>
  </sch:pattern>

If you update that rule to use * instead of . it works just fine:

  <sch:pattern>
    <sch:rule context="sb:SB_Metadata//*[ends-with(name(),'_JD')]">
      <sch:assert test="@unit eq 'julian day'">
        <title>sb:SB_Metadata//.[ends-with(name(),'_JD')]/Rule</title>
        The attribute "<sch:value-of select="name(.)"/>" must be specified with "unit='julian day'".</sch:assert>
    </sch:rule>
  </sch:pattern>
