Rules first become activated, and then are fired. Some activated rules
are never fired, though; their LHSs become untrue before they fire so
they are removed from the agenda. when-activated will evaluate the
salience when the rule is first put onto the agenda; it will then
remain fixed until the rule is either fired or deactivated. If the
rule is later re-activated, the salience will be evaluated again.
