I guess a tool could be written along the following lines:
Inputs:
1) An XSLT transformation that does not invoke fn:collection(),
and only invokes fn:doc() or fn:document() with static URIs
(i.e. URIs that can be made absolute at compile time).
2) The URI for the principle source document (if any)
3) A set of mappings of source-document URIs to schemas
Given these, and a schema-aware XSLT processor, it ought to be
possible to check all XPath are valid with respect to the schemas.
