I see. Then would you say that this is correct:

ISID TSID CID       Action
---------------------------------
 V    0    U      New Session.
 P    0    0      Session Reinstatement.
 P    P    U      Add a connection to a session.
 P    P    P      Connection reinstatement.

Legend:
0    NULL, i.e. 0.
V        Valid.
P        Present.
U        Unique at target.
