I don't think I agree there. What's painful for XQuery group, I imagine, is that the W3C XML Schema group has defined some stuff related to the operations but not enough for the needs of XQuery. If WXS had defined nothing at all for the operations, they could be defined as an extension to W3C XML Schema but here this extension would collide with what's already been defined. WXS here has left us just in the middle of the river... > The ability to add your own primitive types seems to make sense for validation but puts a significant burden on technologies that depend on W3C XML Schema such as XQuery. And the lack of such a system puts a significant burden on the applications...
