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.
