If I could add to that, Ms. Barron, my point was not so much that we should be avoiding or not coming up with new requirements, but just not imposing an extra set of entirely different requirements on a sector of the industry that is already fully traceable.
Again, I think it's the point at which you introduce this and, of course, it does become more complicated, because, really, we're talking about a world where there are a lot of actors rather than just a few actors, so it's more complicated to implement at that stage.
In regard to any thought of a task force or a working group, I think it's going to be, how do you bring in those people who are currently not really participating in the system effectively at the moment?
