I confused by http://relaxng.org/ page and decide that libmsv-java for
schema conversion. But problem exist if you use it as schema validator:

  $ java -jar /usr/share/java/msv-core.jar --help

This is the manifest from msv-core.jar:

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: pbuilder
Build-Jdk: 1.6.0_24
Main-Class: com.sun.msv.driver.textui.Driver
Class-Path: xsdlib-2009.1.jar isorelax-debian.jar relaxngDatatype-debi
 an.jar msv-testharness-2009.1.jar xercesImpl-debian.jar xml-apis-1.4-
 debian.jar ant-debian.jar ant-launcher-debian.jar xml-resolver-debian
 .jar

Apparently the generated Class-Path is incorrect. I'll take care of
fixing it.

Any idea when you will get around to fixing it?  What is the fix?
