Actually, I have responded to requests on this topic, pointing you to the 
XPath 2.0 requirements document. This is largely a set of requests that 
XSLT users have made for extensions to XPath, as I understand it. Since 
XQuery provides these features, XPath has been taking them up. That's an 
incremental, rather than a revolutionary vision. I'm not convinced that 
current XPath users need anything revolutionary. However, support for types 
*is* one of the features that has been requested.

The main places I see XPath being used today are in XSLT patterns, for 
querying XML stored in databases, and as a sublanguage in various 
home-grown systems. I have not seen a lot of commercial support for 
XPointer to date.

Another *very* important vision for XPath 2.0 is to have a more orthogonal 
language, getting rid of a lot of the complicated special casing in XPath 
1.0 that made it difficult to use as a subset of XQuery.
