That's a great question.
The panel turned its mind to that, and our answer was to put the whole thing under the heading of “sustainability”. The meaning of sustainability we had as five pillars. The idea was that you would balance those five things.
What I want to distinguish between the pillars of sustainability and what we have is that the pillars were a test. You had to assess all five ingredients and come out with a view that overall you had something sustainable, a test. Public interest is not really a test, because the criteria are so amorphous that one doesn't have any idea what you're balancing or what you're doing with it. I think we've lost something in where this is headed by moving to public interest and away from sustainability.
