See my reply to "RE:  [Fwd: CLARIFICATION IN XML 2 XML TRANSFORMATION]",
that contains a solution to a similar problem. What you need is to write a
recursive template that tokenizes using COMMA as a delimiter, then on each
token check if that appears in the other list, e.g. with contains(concat(',',
elem1, ','), concat(',', $token, ',')). You can find more info on recursive
templates in the FAQ.
