Hi Tom,

Thanks for your further comment. It is well noted and agreed. Please see inline for additional comment.

The co-authors believe that it is ready for WG LC.

Almost but I fear that there is a step backwards as well.

You still have two
which should probably be

YL>> Yes, thanks for catching this. 

More problematically, you have introduced

    " ...
     The YANG model described in this document is a WSON
     technology-specific YANG model augmenting 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].

Those [RFC..] look like XML/HTML style references which will not do.  A YANG module must be plain text so
is fine in a YANG module but
is not, which is why, in my last comment, I suggested putting a reference to RFC6163 in section 1.4 lest you get an unused reference for the I-D; which you have done, so that is fine, but all those [RFC...] in the YANG module must go.  AFAICS it is only the description clause that has them.

YL>> OK. Will remove the reference brackets within the YANG modules. 

For TE-TOPO, you need to use the same text as you have correctly done on the YANG import statement i.e.

 "RFC YYYY: YANG Data Model for Traffic Engineering (TE) Topologies";

/* Note: The RFC Editor will replace YYYY with the number assigned to the RFC once draft-ietf-teas-yang-te-topo becomes an RFC.*/

YL>> OK. 

Whether this is fixed before or after Last Call is one for the WG Chairs.

I probably said before that the nature of the module, which you are forced to use because of the way that tet: is structured, makes the module very hard to read and that I have not done; I hope to but may never find the time.

YL>> Yes, we are augmenting all groupings from TE-topo model which is in the RFC Editor's Queue now and any fix should've been done before this stage.
