 To prevent this, we establish active context limits for each PAUSER
 privilege level:
 
-* PL0 - 8 active contexts
+* PL0 - 16 active contexts
 * PL1 - 16 active contexts
 
 If a DPE command were to activate a new context such that the total number of
 active contexts in a privilege level is above its active context limit, the
 InvokeDpe command should fail.
 
+At boot Caliptra Runtime FW consumes part of the PL0 active contexts (initially 16) to DeriveContext for:

+   - Mailbox Valid Pauser digest (MBVP) (1)
+   - ROM Stashed Measurements (max 8)

 Further, it is not allowed for PL1 to call DeriveContext with the intent to change locality to PL0's locality; this would increase the number
 of active contexts in PL0's locality, and hence allow PL1 to DOS PL0.
