I think that this I-D needs some more work on it. - I have never seen a YANG module with so few Normative References; in fact, you cannot validly have one with so few. Recall that Normative means you need to understand them in order to understand the I-D and at the very least RFC7950 is in that category and I suspect most of the others are too (but not RFC8340). - IANA Considerations references RFC7950; all this RFC does is tell the reader to go to RFC6020 so that should be the reference here. - The Security Considerations is not current - it lacks any mention of RESTCONF. This will require Normative References to RFC6241, RFC6242, RFC8341 amd RFC8446. RFC6536 is referenced but not in the I-D References The Abstract and Introduction fail to mention whether or not the modules are NMDA-compliant. The YANG module has a lower case 'must' but no indication in the body of the I-D as to how this should be interpreted. The YANG module contains " ...the generic TE topology module [TE-TOPO] based on the information model developed in [RFC7446] and the two encoding documents [RFC7581] and [RFC7579] that developed protocol independent encodings based on [RFC7446]. " AYANG module must be plain text so XML-style references in the module itself are not permitted; all those [....] look suspiciously like references in which case, they must go. The YANG module 'import' statements import ietf-network { prefix "nw"; } import ietf-network-topology { prefix "nt"; } import ietf-te-topology { prefix "tet"; } import ietf-layer0-types { prefix "layer0-types"; need to reference the RFC where these modules can be found, e.g. import ietf-network { prefix "nw"; reference "RFC 8345: A YANG Data Model for Network Topologies"; } The YANG module references RFC6163 RFC6205 RFC7698 none of which are in the References. 'reference' statements in the module must be plain text but the document must be referenced from the body of the I-D with a suitable entry in the References of the I-D. module ietf-layer0-types lacks a YANG version statement.
