Actually, an easy fix: Write your random-number extension so it *IS* functional -- have it accept an argument, and feed it the last number returned. That creates the data dependency which guarantees order of (repeated) execution.
If it chooses to ignore that value, fine -- but this tells XSLT that the calls are distinct. ______________________________________ "...
