I have not seen any definitions like that attached to it. I think you want to have it as flexible as possible so that it can run in a number of different directions. You don't want to have it driven by pure job numbers or geographical locations.
I think you want to make sure that it recognizes that we're all competing in a global economy and that these decisions are being made on that global basis. So you have to find a way to make it as flexible as possible.
