XPath validation against a schema rather that against an instance

Heres a question I was asked today which struck me:

>Is there any way I can validate a XPATH against a XML Schema (and not
>against the XML document)

I don't know of anything like this. I can see why it would be a useful static
sanity check of XPath usage in some contexts. I.e. "warning: //foo can never
match in schema XXX because there is no 'foo'".

Anybody got any pointers?
