Re: second implementation of XSLT 2.0?
There are advancing XSL-T implementations as mentioned in this thread, but I don't see how running a transform or two with each engine answers the questions of interest: whether they are interoperable, and that the specification is implementable.
The W3C has never been the best organization for test suites and interoperability. For instance they do not require even one complete implementation before advancing to REC, only that each feature be independently implemented. It is possible for a W3C spec to be actively self-contradictory as long as different implementations implement different internally consistent subsets.
Different working groups and specs have different informal criteria for this. Some WGs produce very reliable test suites and require 100% passage. Other produce no test suite at all. And still others are somewhere in between. Most groups including the XPath/XSLT/XQuery group are improving their process over time--XPath 1.0 had no test suite at all--but they aren't perfect yet.
