The only point I want to make is that a great deal of this entire regime depends on the goodwill and honesty of the people involved in it. The whole review system of the confidential document depends on what people are telling us being actually the truth. We don't audit the documents; we review them and try to make the appropriate arrangements. So the whole structure depends a very great deal on the goodwill and integrity of the people involved.
My experience thus far is not that there has been no difficulty, but by and large, people in fact illustrate the integrity that was intended. There are exceptions, clearly, and if the clause you mentioned is misused, it's like any other clause that's misused; it will weaken the effect.
