Re: [xsl] Difficulty with document() and for-each scope

That's the conclusion I reached too.

Yes, that's correct - XSLT 1.0

Aha, that was just what I was looking for - it didn't click that doing a 
for-each on the root node would only cause one "iteration".  At this 
point I'm only using it in one place, so I can live with the messiness 
(it's still cleaner than copying and pasting the same block 12 times!)

Thanks for your help!

Adam.
