Re: [Teas] Fwd: IETF WG state changed for draft-ietf-teas-yang-te-topo

[Lou Berger <[e-mail]>]

Hi Igor, (and authors)

     Can you point to where in the archive this discussion took place - 
https://mailarchive.ietf.org/arch/browse/teas/?q=source%20instance isn't 
yielding helpful information.  It's also fine for the authors to make 
the case for the change now if a suitable reference can't be found.

Lou

PS For future reference, technical changes are generally now allowed 
once a document has been approved by the IESG, and even more rarely once 
in the RFC editor queue.  (This is nothing new - I remember having quite 
a discussion back when Jon P. was RFC editor and having to convince him 
that moving the '|' in a packet format half a bit over in a drawing 
didn't require moving the doc out of the RFC editor queue even though 
half bits clearly didn't match the text.)
