I haven't looked at Resolution 1497, frankly, probably since 2003, so I would add that caveat. What clause 11 does is it frankly allows—it really comes close and I think others would say it goes to allowing—Canadian Armed Forces to violate the letter and spirit of the treaty, which says don't use cluster munitions. And there was in West Africa, I believe it was in Sierra Leone, if I'm not mistaken, an instance where some UN forces used cluster munitions and were condemned for that.
If you would like me to go back and take a look at Resolution 1497 and examine your question a little more closely, I could get you a written response if you'd like.
