ClamshellSM.c in AMSS uses Class ID... accept Mastermind.
Mastermind is only controlled by App NAME.
So if PlayEx for example would be also startable as application/mastermind.
You can use Mastermind for prevent Clamshell closing to kill App.
So it would work on E81C. On both PK and FK Version. Because both have this mastermind String.
SF71 not.
