It is a great pity that the XPath possibilities are restricted in the March 30 recommendation because it clearly limits the expressiveness.

We already have developed an xml-java data-binding tool that supports the full XPath 1.0 specification and can not do without it. Does this mean that our schema files are no longer valid? Wouldn't it be possible to have another conformance level for validators that demands full XPath support?

PS: I can not follow the complexity argument because there are already several open source XSLT processors that contain XPath implementations and we also implemented one in our data-binding tool.
