It's a research prototype.
My current project uses schema only, no WSDL, and with relax-ng unable
to handle inheritance I've abandoned relax-ws in favor of plain XSD
which by itself is not so bad.
I still think there's a great opportunity for this concept, and were I
doing more WSDL I'd be using it to at least kick-start a project. I'd
like to try replace relax-ng compact schema with something else that
also leverages the XSD types, but don't have time to start that just
yet. It also depends on the interest level of others ;)
