As others have pointed out, the Kaysian method (originally used with XPath
1.0) has been around the last seven years.
Also, "intersect" and "except" are operators in the standard XPath 2.0
language, for which several implementations exist.
Embedded in XSLT 2.0: Saxon, Gestalt, Altova
Embedded in XQuery 1.0 -- many.

Does anybody know any implementation of XPaths that supports path
intersection and difference?
