Status update on draft-ietf-teas-yang-l3-te-topo

Current Status:

  *  The updated revision -06 was posted on March 8, 2020:
     - Editorial changes.
  *  Corordinated with ietf-eth-te-topology and ietf-te-mpls-tp-topo
     for the augmentation of ietf-te-topology
     - ietf-te-topology does not need to be changed.
  *  Answered YANG doctor's review comments.

Open Issues:

  *   None.

<tp>

I started  to review this and have given up,  I cannot make sense of section 2, which I see as fundamental to understanding the I-D.
 Thus 
The YANG modulues  ietf-l3-te-topology ...
These two modules augment ietf-l3-te topology
No they don't!  This augments 
ietf-l3-unicast-topology
which is quite different and I find this confusion elsewhere in section two. Thus
Relationship  between Layer 3 Topology and TE Topology
Is that Layer 3 TE Topology or ietf-network-topology?  I think that many if not most  references to TE Topology are ambiguous and need clarifying - is the reference to Layer 3 TE Topology to  ietf-network-topology?

Some of the words are quirky and this website is determined not to let me put them into an e-mail but here goes.

modulues
topoology
moducment
Local ink

Tom Petch
Next Steps:


  *  Update the model to sync with the referenced models like draft-ietf-teas-yang-te-types if there are any changes.
  *  Welcome further reviews and suggestions.
  *  Working Group Last Call after completing the above.

Thanks,
- Xufeng
