Re: http://lists.w3.org/Archives/Public/public-rif-wg/2007Jun/0003.html
and
     http://lists.w3.org/Archives/Public/public-rif-wg/2007Jun/0004.html

... I think this needs some thought, especially something like 
aggregates! Aggregates can also be (and are by implemented rule 
systems!) on predicate extensions instead o lists.
  Also, we do not have a datatype for lists yet, do we? (mainly asking 
because I might have missed that on the second day of the f2f in case...)
