I think the answer > is YES? [Med] YANG modules defined in the IETF so far are defined in PS documents, even when covering protocols that are in Info/Exp. An example is RFC9105. You may refer to https://mailarchive.ietf.org/arch/msg/opsawg/7E9g02ZwMt5z9PT1vgSai4kW42U/ or the discussion at the time in the IESG. The key point is that a YANG module (independent of the underlying objects it manipulates) is about making two peers (client/server) interoperable. The following usage in Section 3 (inherited from 8407): CURRENT: There are three usage scenarios for YANG that can appear in an I-D or RFC: o normative module or submodule o example module or submodule o example YANG fragment not part of any module or submodule But > this is not clear.

[Med] This is a matter of taste, but more importantly follow the practice used in rfc8407 vs 6087. > > 688 Unless the modules comply with [RFC8791] or define YANG > extensions > 689 (e.g., [RFC7952]), the security section MUST be modeled > after the > 690 latest approved template (available at > 691 > <major> I am not sure if a wiki pointer is appropriate here. [Med] This practice is implemented and followed since many years now (including RFC editor, etc.). We need a stable reference to maintain the template out of the RFC itself. A reason why the template is maintained here and not completely offloaded is that we received a request from the IETF trust that we addressed (this text is used outside the IETF).

[Med] This part is untouched from 8407. The key part of the text you quoted is "normative modules". Other types (e.g., example modules) are not concerned to follow the full guidance. > > 1605 4.7.

Can you please clarify? [Med] Idem as previous one, this is inherited from 8407. As clarified in that same section, the reasoning is vs. published module, which is defined as follows: o published: A stable release of a module or submodule. For example, the "Request for Comments" described in Section 2.1 of [RFC2026] is considered a stable publication. > > 1656 The "organization" statement MUST be present.

[Med] Updated to reference Section 5.3, where we have: XML namespaces for private modules are assigned by the organization owning the module without a central registry. Namespace URIs MUST be chosen so they cannot collide with standard or other enterprise namespaces -- for example, by using the enterprise or organization name in the namespace. > > 3154 The initial version of this YANG module is part of > RFC IIII; see > 3155 the RFC itself for full legal notices. > > <minor> This RFC IIII is used here and other places in the context > of the IANA > related aspects.
