Of course, a lot of the gains you claim come from moving from XSLT 1.0 to XSLT 2.0 can be gained by simply extending XSLT's function library. Look at http://www.exslt.org or http://msdn.microsoft.com/library/en-us/dnexxml/html/xml05192003.asp for examples of what I mean.

As languages, XSLT 1.0 and XPath 1.0 are very much flawed. Think about
the RTF hell, the minimal function library, the heavy syntax for
conditionals and calling templates, the inability to iterate through
anything but node-sets, etc. I see XSLT 2.0 and XPath 2.0 as much
needed fixes to the original specifications. An XSTL 2.0 program
(stylesheet) of medium to high complexity will be much easier to write
and understand than the same program in XSLT 1.0. Download Saxon 7 and
play with it to see for yourself.

Also, there is a natural need for more functionality. If you were to
look at the evolution of Java over the last eight years, what would
you find out?  My guess is that Java has largely beaten the market
growth ;-)
