I suppose that's understandable, inasmuch as XSLT 2.0 in general is 
being pulled in the direction of a generalized data processing language 
and not just a tree transformation language. (What with xsl:for-each no 
longer selecting -- or, some day, template rules no longer matching -- 
only nodes.)

Yet I dare say it may help to keep a rough distinction in mind in any case.

So does this also mean the concepts of "current node list" etc. go by 
the boards? (Now going to look and see.)

Cheers,
Wendell
