set union? xslt 2.0

Stylesheet parameter of the form "term1|term2|data" I.e. one or more
sought 'terms' So could be just 'term1'

xml source of the form

<skillarea targets="data|general">

I.e. for grouped elements, the terms may or may not overlap with
the targets.

Problem:
   How to select and apply templates to the skillarea elements which
   have at least one
 item in common with the terms?
Either in an apply-templates select attribute or perhaps
better in a 'template match=""' attribute.




E.g. the terms and targets overlap here with the item 'data' and
hence are wanted in the output.

TIA
