If I could follow up on Ms. Mathyssen's point on the universality of service, from the U.S. witnesses we talked to, they had indicated there is more flexibility, obviously, than in our system, and I know we're moving in that direction, but in some cases they allow a limited duty status.
Are you familiar with the U.S. model of universality of service? Do you think this is something we should be moving towards, or are we moving towards it? What's your take on that?
