  This aggregator calculates the sum of the values of a selected aggregate parameter of a called pattern. The aggregate parameter is selected with the '#' symbol; the aggregate parameter must not be used outside the aggregator call. The other parameters of the call might be bound or unbound; bound parameters limit the matches to consider for the summation.
