  Well there is the relatively harsh (but fair at the time) comparison
he posted on the ietf-xml-use mailing list
  http://www.imc.org/ietf-xml-use/mail-archive/msg00217.html

Though the XML Schemas implementation have improved since, still
a lot of the argumentation still makes a lot of sense from a
technical viewpoint IMHO.

  Since it's far far easier to validate the semantic of a Relax-NG
Schemas it seems to me that doing the opposite way (i.e. having
the Relax-NG master and relying on automatic generation for the XSD)
is more likely to garantee the semantic of both schemas,
