RE: [Seamoby] CAR Discovery Requirements

Hi Phil and Hesham,

some comments:
- requirements shouldn't mandate certain solutions. What Phil proposed
was to make certain solutions mandatory. This is not about being vague
or not. This is retricting the solutions (maybe for a certain reason).

- making the 'usage' or 'accomodation' of mobility management features
a MUST restricts the solution space, too. Is a solution prohibited, only

because it does not rely on certain mobility management features, even
if
the solution might be easier?

Regards,

Dirk
