Section 3.1.3. says:

      ENCR_NULL                11        [RFC2410]       MAY

It should say:

      ENCR_NULL                11        [RFC2410]       MUST NOT

Notes:

ENCR_NULL is MUST NOT for IKEv2, as RFC4306 specifies that ENCR_NULL MUST NOT be used as IKE encryption algorithm (RFC4306 section 5).
