In short : we're getting there:
- Their models are compatible with LNEs as they are ignorant of them, which 
is of course part of the value/strength of our proposed approach.
- WRT NIs, we have terminology and end structure alignment with 
draft-openconfig-rtgwg-network-instance and my hope is for the work to 
fully converge once Rob has time to spend on schema mount.

Also would be good to hear from the open config folks directly - - Rob and 
Anees, do you want to add anything?
