Ave allows the user to compute
additional attributes for abstract events once the matching is done.
The syntax of the command is
with <abstract-event> foreach <descendant-event>
compute <attribute-name> = <expression>;
which computes an attribute named attribute-name according to the
evaluation of the expresion foreach descendant of abstract-event
named by descendant-event.
