RE: Problem with obtaining distinct values from a var

This is dead easy in XSLT 2.0, but assuming that you want a 1.0 solution,
the only common grouping technique that works on a node-set that might
contain nodes from different documents is Ken Holman's variable-based
grouping technique. Google on that, or see
