Section 3.4 says:

Reset Generation
    3.  If the connection is in a synchronized state (ESTABLISHED,
    FIN-WAIT-1, FIN-WAIT-2, CLOSE-WAIT, CLOSING, LAST-ACK, TIME-WAIT),
    any unacceptable segment (out of window sequence number or
    unacceptible acknowledgment number) must elicit only an empty
    acknowledgment segment containing the current send-sequence number
    and an acknowledgment indicating the next sequence number expected
    to be received, and the connection remains in the same state.

    If an incoming segment has a security level, or compartment, or
    precedence which does not exactly match the level, and compartment,
    and precedence requested for the connection,a reset is sent and
    connection goes to the CLOSED state. The reset takes its sequence
    number from the ACK field of the incoming segment.

It should say:
