Message authorization in conf profiles

Should we be more 
explicit about the level of support expected for message authorization, as 
discussed in AS4 SC:
 
 The Gateway conf 
profiles say:

  
  Support for message 
  authorization at P-Mode level (see 7.10 in [ebMS3]) using wsse:UsernameToken 
  profile, in particular authorization of the Pull signal for a particular 
  MPC.
Should we say instead:
Support for message authorization 
at P-Mode level (see 7.10 in [ebMS3]) using wsse:UsernameToken profile. Authorization of the Pull signal - for a particular MPC - must be 
supported at minimum.
