Where's Sun's RELAX NG Converter?

["Jeff Lowery" <jlowery@myrio.com>]

Looking to convert an XSD to RELAX NG. Kawaguchi of Sun wrote a converter back in aught-two, but all the links I can find point to:

http://wwws.sun.com/software/xml/developers/relaxngconverter

 

Which redirects to:

http://java.sun.com/xml/

 

Thought maybe it was now included in the JAXP or JAXB suites, but I can’t find. Maybe keener eyes can spot it?
