No problem with speed.
   <grin/> Guess you mean

This is the 'odd' meaning of = in xslt 2?
If any item on LHS is present in RHS then = returns true.

  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?
