<DL>
<DD>Delivers the list of criteria which is able for this operator. Please note that
  all criteria in the list must be freshly instantiated since no copy is created
  in different runs of this operator. This is important in order to not mess up
  the results.
  
  This method must not return null but should return an empty list in this case.
