Sorry for the delay in responding to this...

LOGGED_IN marks the beginning of the full-feature phase, IN_LOGOUT
and LOGOUT_REQUESTED (states S6 and S8) also are full-feature phase
states.

Logout may have digests if so negotiated -  please refer section 9.14.

In short, every PDU that is used in FFP (i.e. any PDU other than Login and Login 
Response PDUs) may have digests if so negotiated - section 11.1 clearly states this.

Regards.
