Actually, I was thinking Proposed Standard, as an Applicability Statement (see RFC 2026, Section 3.2). BCP would be an alternative also. I think that, *if this is the way the WG decides to go*, it would not require extensive document changes. I see it as something like this: ---- a. Make udpzero a Proposed Standard and call it an Applicability Statement, or make it a BCP. b. Put the 2119 language into udpzero Section 5.1, instead of in udpchecksums Section 5. c. Change the intro paragraph in udpzero Section 5: OLD This section identifies requirements for the protocols that are transported over a transport connection that does not perform a UDP checksum calculation to verify the integrity at the transport endpoints. NEW (for AS) This section is an Applicability Statement that identifies REQUIRED restrictions on the use of techniques that involve not performing UDP checksum calculations to verify the integrity at the transport endpoints. NEW (for BCP) This section specifies best current practice for REQUIRED restrictions on the use of techniques that involve not performing UDP checksum calculations to verify the integrity at the transport endpoints. (Or some similar sort of language to indicate that the restrictions must be followed.) d. Change udpchecksums Section 5 to remove the numbered list and the RFC Editor note, and to make this other change: OLD However, some protocols, such as tunneling protocols that use UDP as a tunnel encapsulation, MAY omit computing the UDP checksum of the encapsulating UDP header and set it to zero, subject to the constraints described in RFCXXXX. NEW However, some protocols, such as tunneling protocols that use UDP as a tunnel encapsulation, MAY omit computing the UDP checksum of the encapsulating UDP header and set it to zero, subject to the constraints described in [I-D.ietf-6man-udpzero], Section 5.1. e. Make udpzero a normative reference. ---- With those changes, most of udpzero remains as informational exposition leading up to Section 5, and Section 5 is the normative part.
