In addition to Liam's list I think there are a couple more vital features
one needs to get a taste of in XSLT 2.0 or XSLT 3.0, if one has been
subsisting on an XSLT 1.0 diet:

* <xsl:for-each-group> and its uses
* temporary trees - no more extension node-set() function needed (huge!)
* regex support in functions and xsl:analyze-string
* tunnel parameters?

I am sure there is more ... and I think anyone still using XSLT 1.0 owes it
to eirself to learn that XSLT 2.0 has had these features since 2007 (and
they work).

Cheers, Wendell
