I'm not sure I understand. The cross section information in HepMC would 
not change. It would still give the the estimate of the actual cross 
section of the recorded events. The only thing that changes is that the 
number of discarded zero-weight events is reported through the event 
numbers. In what way is ATLAS using the event numbers now?
