if you're worried about repeatedly tokenizing the attributes probably
you can optimise this with a key or some such, or perhaps saxon will
optimise for you behind the scenes or perhaps it's fast enough anyway.

No problem with speed.
    <grin/>  Guess you mean
<xsl:template
   match="skillarea[tokenize(@targets,'|')=tokenize($param,'|')]"/>

This is the 'odd' meaning of = in xslt 2?

If any item on LHS is present in RHS then = returns true.

Issue:
   What happens with tokenize when the separator is missing?
empty set?

   Resolve using if contains(@target,'|') then tokenize.... else ...
Getting rather messy since either could be a list.

I think this idea would work without a separator?
param = "term1 term 2"
@target="term1 oddone"

Would the equality work then? Currently strings, is this a case
where a sequence is needed?
