I see Mr. Lee's point in terms of where he's coming from with respect to the question, but as Mr. Yost has indicated, these types of issues certainly can be covered under the regulations. A regulation would actually identify what we were using in terms of how the qualifications work, and would indicate also that somewhere down the line they would make sure they were updating and approving whatever mechanism was being used from an international perspective.
It seems to me you're right, but your concerns can be met based on a regulation put after the legislation is passed.
