Hi Wendell,
Using key() is sooooo much easier than recursive templates.

I originally thought of doing this (assuming I understand you) but
then I got back to the problem where I have multiple node-sets with
no obvious (to me?) way to combine them into a single node-set, though
I was eventually able to combine them using recursive template calls.
Is there a simpler approach to combine a variable number of node-sets
into a single node-set (without using extensions)?
Thanks again,

I see you've picked up the nice feature that that second argument can
return a node-set and not be treated as a string.
(Even if it didn't, you could still iterate over the column children and
use . for that second argument. ;-)
But as I said, we use keys so much for grouping, we forget the general case
of what they're really for, "a way to work with documents that contain an
implicit cross-reference structure" [XSLT 12].
Cheers,
Wendell
