I've noticed a few odd items about Papal warnings.
1) If you are sieging a city/castle and the Pope warns you to stop fighting, you can keep up the seige and take the provice so long as you don't assault. Logically the warning should mean "Stop the seige", but thats not how its handled.
2) Blockades can be kept during a Papal warning without you getting in trouble with the Pope, but you can't start one without getting him upset.
3) When he gives the warning, the only types of combat you can be involved with are siege related without failing the mission and getting the Pope upset. That means you can sally forth to get rid of a sieging army or fight an army that sallies forth, but you can't fight and open battle even if you are the one defending. I've had a couple cases where I had small units moving on the campaign map that got attacked. If I wasn't able to withdraw and I was stuck fighting, I'd get the Pope pissed at me.
4) If you bribe your way into better standings with the Pope than what your enemy has, you can continue fighting with them (and accept the loss of the mission) without worrying much about really loosing standing. This may not always be the case but I've yet to get excommunicated for doing so.
This may not be intuitive, but its what I've observed in the game and, to me, definitly seems to be abusable. Now if we could just figure out when other factions recieve Papal warnings.
