Thanks Tom for feedback and clarification, not actually familiar with IEEE process and just thought IEEE 802.1 is assigned to do the formal job. Maybe I missed anything and will check my AD.
If you have any suggestion, please also let us know, thanks!

Hi, Magnus and Rob:
Thanks to Sue for helping reaching IEEE community, we have received IEEE802.1 Feedback on draft-ietf-i2rs-yang-l2-network-topology-15

Well yes, but as the chain of e-mails makes clear this is informal feedback from an individual in IEEE 802.1 YANGsters group and not a formal liaison response (which I expect is fine).  My sense is that the IEEE has a somewhat different view of Bridge ID and VLAN ID to that which I held beforehand from IETF I-D and will look at other uses of VLAN ID, in particular, in a different light as a result.  Perhaps it is time I re-read 802.1Q!

Tom Petch
and address them in v-17 and v-18
The latest update is available at:
Let us know if you can clear the DISCUSS now, thanks.

Sue, I raised a discuss on this just to ensure that IESG would discuss the issue today. I raised it based on the Glenn Parsons request on the IEEE-IETF mailing list and that there where apparently some confusion.

So I don't really know which failures did occur in this case. I think it would be good to analyze it. I would suspect a combination of issues. Likely including that turn over among AD makes people loose history and process.

>From my personal perspective, I as AD would appreciate a WG chairs that 
out to the AD when they thing there might be need for coordination with external bodies. I understand that for this document they might not be as clear.
