Looking for XSLT to "Pretty Print" XSDs as Docbook

I am lookingh for a way to use an XSLT to take an XSD and produce the docbook xml that would produce a nicely formatted human readable description of the contents of the XSD. This would be similar to what is currently done by XS3P http://en.wikipedia.org/wiki/Xs3p. Instead of producing XHTML like XS3P, it would produce Docbook XML that could be included in a larger document.
