I think if we're trying to articulate the objectives in a general statement in advance, one could read that statement in terms of the pursuit of particular economic, competitive, efficient...and competing against those efficiency-type objectives would be safe and sustainable. Sometimes those two objectives wouldn't necessarily be consistent, and I don't think anyone here wants us to argue in favour of an economic, efficient, competitive system at the expense of safety.
I think, just to make it clear, that is the reason that kind of language is being requested, so that we understand the balance we're trying to find.
As far as the argument that we're trying to make it clearer goes, I don't think we want to make it clearer at the expense of safety or economic integrity.
