Sure, Saxon-SA does this as part of schema-aware XSLT and XQuery processing,
and the functionality could be packaged to do what you are asking. Well, it
does almost this: Given an XPath expression and a schema type (typically a
complex type), Saxon will tell you whether the expression is capable of
selecting anything when applied to a context node of that type.

No, the fact that XSD uses XPath for defining assertions doesn't directly
help with your requirement.
