I'm confused. XSD and RNG are to a large degree orthogonal - XSD is 
a type system, RNG is an a schema language for XML. Perhaps XSD is 
being conflated with WXS?

Well less than two years ago, RNG was a fringe technology. Now it's 
on the rise - I'm confident over the next two years RNG + son of XSD 
will be the way we describe content models for web services. So I 
suspect you'll see support for RNG in these tools. Although, if 
policy makers are being diven by tools instead of technologies, 
arguably they're putting the cart before the horse  - but that's a 
different discussion.
