Actually since XPath 3.0 is not yet a W3C Recommendation, and XSLT 3 is stilla Working Draft, it would be premature for anyone to claim conformance. > And it's not free.

If you see XPath as a domain-specific language for pointing into XML documents, or into XDM trees, it's hard to see a lot of people wanting to pay for something if all it did was save them money, improve reliability, reduce costs and speed up development. Unless they had an ounce or more of business sense that is :-) > So, if there is no free, fully-compliant XSLT/XPath 3.0 processor, I > doubt that XSLT/XPath 3.0 will get any uptake by the people I work > with. For XPath 3.1 I really hope we can define a minimal conformance level that's close to XPath 1, so that we might actually get more implementations. It's probably too late for XPath 3, but I admit I think it's insane for us to require programmers to implement closures in XPath for e.g. XPointer schemes. There _are_ some zero-dollar XPath 2 implementations floating around, e.g. there's one that's used in Eclipse, although I don't know how complete it is. There's actually slightly more on the XQuery side, with e.g. PHP APIs for both BaseX and Zorba, which may help get XQuery and XPath into Web servers.
