I like this, and it matches the "same results" modification I previously mentionned -- I you think of the results as state transitions. >From Steve's original email: "Same attack, same software flaw = same vulnerability." modification: "Same attack, same results of the attack = same record". So, I'm afraid there are really three choices. Pascal
