The UN discourages it. In fact, our policy is to discourage caveats. We are allowed to have them, and we do from time to time insist on them.
I'd like to add one more thing. One of the important things we've learned has to do with child soldiers. One of the most challenging things any Canadian or other UN uniformed peacekeeper faces is coming face to face with a 14-year-old carrying a weapon, and knowing what to do. That's one of the reasons why we're rolling out this Vancouver principles doctrine: to try to engage an international coalition of countries to better address those issues.
