Section 4.1 says:

pcePcepSessState OBJECT-TYPE
       SYNTAX      INTEGER {
                      tcpPending(1),
                      openWait(2),
                      keepWait(3),
                      sessionUp(4)
                   }
       MAX-ACCESS  read-only
       STATUS      current
       DESCRIPTION
           "The current state of the session.

            The set of possible states excludes the idle state since
            entries do not exist in this table in the idle state."
       ::= { pcePcepSessEntry 3 }

It should say:

pcePcepSessState OBJECT-TYPE
       SYNTAX      INTEGER {
		      idle(0),
                      tcpPending(1),
                      openWait(2),
                      keepWait(3),
                      sessionUp(4)
                   }
       MAX-ACCESS  read-only
       STATUS      current
       DESCRIPTION
           "The current state of the session."
       ::= { pcePcepSessEntry 3 }	

Notes:

As per security consideration, if PCE needs to allow incomming connections from only known PCCs.
Source addresses of PCCs are configured on PCE. If PCEP session on PCE goes down with configured PCCs.
PCE needs to raise notification pcePcepSessDown (i.e. details mentioned below).
Issue is whiling sending the notification pcePcepSessDown, as session state (pcePcepSessState) defined in RFC doesn't include idle state.
I suggest to include idle(0) state for pcePcepSessState.


pcePcepSessDown NOTIFICATION-TYPE
OBJECTS {
pcePcepSessState,
pcePcepSessStateLastChange
}
STATUS current
DESCRIPTION
"This notification is sent when the value of
pcePcepSessState leaves the sessionUp state."
::= { pcePcepNotifications 2 }
