Hi Francesca,

Thanks for picking this up and turning it serious.

There is a BCP14 alert here, though:


>   A profile MAY want to prepare for being combined with others by clearly specifying 
>   its security requirements.

The BCP14 keyword MAY would be appropriate to announce some behavior that a peer MUST prepare for.  But that is not what we are trying to say here.  Maybe:

NEW^N:
>   Profiles are expected to prepare for being combined with others by clearly specifying 
>   their security requirements.


(Stating may be another alternative word for specifying.)

Grüße, Carsten
