Schematron validation in Java

I'd like to be able to use both schema and schmatron validation for 
messages in a Java web service environment. Schema validation is easy, 
but schematron is proving to be a real problem. I've tried using the 
XSLTs from http://www.schematron.com/ using both the built-in Java 5 and 
6 XSLT handling (based on Xalan, I believe) and also the Saxon 9.1 XSLT 
implementation, and both ways the XSLTs seem to work ok but the final 
output I get from running the generated validation XSLT on a sample 
document is just:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<svrl:schematron-output xmlns:schold="http://www.ascc.net/xml/schematron"
                        xmlns:iso="http://purl.oclc.org/dsdl/schematron"
                        xmlns:cl="xxx"
                        xmlns:saxon="http://saxon.sf.net/"
                        xmlns:svrl="http://purl.oclc.org/dsdl/svrl"
                        xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                        xmlns:xs="http://www.w3.org/2001/XMLSchema"
                        title="Rule set for Application Fulfillment"
                        schemaVersion="ISO19757-3"><!--  Â
          Â
          Â
         --><svrl:ns-prefix-in-attribute-values uri="xx" prefix="cl"/>
   <svrl:active-pattern/>
</svrl:schematron-output>

(namespace removed, since it's a client schema) whether the document is 
schematron-valid or not. Does anyone have any suggestions as to what I 
might be doing wrong? Or for any other ways to get ISO Schematron 
validation in Java? Or even if this is the expected output?

Thanks,

  - Dennis
