Section 4.1 says:
o Protocol ID (1 octet) MUST be 1, as this message is related to an IKE SA.
It should say:
o Protocol ID (1 octet) MUST be 0.
RFC5996 (IKEv2) in section 3.10 while describing Protocol ID field in Notify Payload specifies that "If the SPI field is empty, this field MUST be sent as zero and MUST be ignored on receipt". As this RFC requires SPI field to be empty (later in section 4.1), Protocol ID should be zero to be consistent with RFC5996.
