[Openid-specs-mobile-profile] Mobile Connect sector_identifier_uri

A sector_id is an RP parameter, not an IdP parameter. So it doesn't make sense to have a sector_id "for all MNOs in one country".

A group of MNOs could agree to calculate subs in the same way from an RP's sector_id so they all issue the same subs. But any RPs relying on that to make Account Porting "easy" are basically ensuring the RP will fail to recognise Porting more widely.

It is probably the Imp of the Perverse sitting on my shoulder making me writing this, but ...

Mobile Connect could specify a sector_identifier_uri for all MNOs in one country <cough/>
and specify a Pairwise Identifier Algorithm that yields in "portable" subs thus making Account Porting easier. Maybe too easy...
