The spec of XSLT2 was actually going to work this angle and move XSLT more into a space of a general purpose language. However, lots of people in the XSLT community realized that XSLT is made to do one thing and that's XML tranformation. XSLT(1) did that pretty well to a certain extend. The spec for XSLT2 never really took off and I don't think there are notable implementations and support out there other than from the spec's leading author's (Michael Kay) and his tool Saxon.
