Exactly. Remember that Don's original comments on XML Schema were
addressed specifically towards Web Services, a task where we clearly
need a rich type system to achieve interoperability between toolkits and
other applications that cross programming language specific type
systems.

I wouldn't call the WS community a large niche.

The fact that the W3C has assumed XML Schema in layered specs like XPath
2.0, XSLT 2.0, and XML Query (the original argument) says a lot about
the technical merits considering the W3C process.
