Are you using Saxon to do the validation, or Xerces?

If I run this pipeline with Saxon validation:

<p:declare-step version='1.0' name="main"
		xmlns:p="http://www.w3.org/ns/xproc"
		xmlns:ex="http://xproc.org/ns/xproc/ex">
  <p:input port="source">
    <p:document href="test/invalid.xml"/>
  </p:input>
  <p:output port="result"/>

  <p:try>
    <p:group>
      <p:validate-with-xml-schema>
        <p:input port="schema">
          <p:document href="test/xsd-schema.xsd"/>
        </p:input>
      </p:validate-with-xml-schema>
    </p:group>
    <p:catch name="catch">
      <p:error code="ex:foo">
        <p:input port="source">
          <p:pipe step="catch" port="error"/>
        </p:input>
      </p:error>
    </p:catch>
  </p:try>
</p:declare-step>

I get reasonable looking errors on stderr:

Is that not what you get?

With Xerces, the errors don't appear. That's a bug, but Xerces validation is
pretty sketchy so it's probably not the only bug.

                                        Be seeing you,
                                          norm
