I'm having trouble wrapping my head around that one.  If the processing is
also expensive, I'll use that as an excuse to run from this solution...

Consider me to have asked again.  Still, the only reason I need it in a
single pass is because I don't know how to do a double pass -- in xslt or in
java, which is going to be driving this whole wagon.  I would like to avoid
extension functions, but (imho) a solved problem is better than an unsolved
one, so I'll take what I can get.

Thanks again
