I'm involved in a large cross-environment (IBM, Siebel, Microsoft, others)
Web services implimentation, and we've been heavily using XSD for message
specificaitons .... but have been clobbered often by weak support for XSD
(and WSDL) across the different environments.
But we would not consider RNG, as there's no support in the toolsets the
development teams use.
I imagine we'd be giving RNG a try if if were adopted by our commercial
partners, but as it isn't, we shall stick with XSD.
