Xalan supports XSLT 1.0, which is the only W3C-blessed version of XSLT currently in existance.
XSLT 1.1 was a proposal that the W3C has decided not to pursue. XSLT 2.0 is currently a Working Draft being developed jointly with the XML Query group. It involves some fairly significant architectural changes to track datatypes and so on. Folks have been looking at what would be involved to extend Xalan to support XSLT 2; current estimate is that it is doable but not trival. ______________________________________ Joe Kesselman / IBM Research
