Things such as what you're suggesting, or (similarly) nasty compound 
keys etc. are sometimes a necessary evil in XSLT 1.0, but in your 
case I really think there's a simpler way to do it. Especially in 
XSLT 2.0. (Which you're using, correct?)

Could you be bothered to restate your problem with a concise example? 
At a minimum, show us some code for source and desired result.

The English-language description of the problem is good, only not 
quite enough -- it's enough for us to track your thinking up to this 
point and say "it looks reasonable" -- to verify you're on the right 
track. But that's all: to get you over the top, particularly if no 
errors of XSLT-reasoning jump out, we'd like to demonstrate. Which we 
can do if we have a realistic (but miniature) example to work over. 
Add some demo source code to the description, plus even some XSLT 
that almost works, and you're much more likely to get good help.

The list (like all lists, I imagine) works best if you consider it to 
be "stateless", even within a thread. Write up your problem so that 
the XSLT guru who has not been reading can hop right in and help you. 
It's happened before. (And then she went off to bigger and better things.)

Cheers,
Wendell
