in the past (and we are talking distant past now in internet time)
there were some XSLT processors that needed to be nudged with number()
when doing path...I seem to have a unit test for this (as i did the
exslt math modules) somewhere.

Since u didnt tell me which implementation you were using (and I just
briefly scanned your email)  the brain cell came up with number()
function....listen to Florent as he is right in this situation.
