Speaking of pre-negotiations, I think there's controversy over a negative-list versus positive-list approach. One of the criticisms of a negative-list approach, which Canada has been taking with CIDA, is that it does exactly that, it predetermines. Because if we don't specifically exclude something, goods and services that have not even been invented yet, that we're not even aware of will be subject to free trade because of a negative-list approach.
Do you have any comment on that approach or that concern?
