Lovely.  And here I am thinking I was a jaded XSLT expert who knew how to pull every trick in the book from its reduced instruction set (thanks, Mike for the trope).

I should know better than to say there isn't a built-in solution to something in XSLT until David, Jeni and Mike have spoken  :-)

That geek praise having been dished out, I still think this is an area best covered by a cleanly-specified EXSLT function.
