Re: [sfc] Fwd: IETF WG state changed for draft-ietf-sfc-serviceid-header

I am not confident that I follow your reasoning.   So let me restate 
slightly, and then add some observations and questions.

You appear to be observing that the information as to what serviceID 
could come from the control plane framework.  Is that what you are 
getting at?

That draft has not been updated in more than 3 years, expired for 2.5 
years.  It does not appear that the working group has any interest in 
the document.  When it was last considered, there was a lot of 
controversey about the draft, and if I recall correctly no agreement 
that it was structured the right way.

Our approach to metadata, and for that matter to SPFID selection, and to 
the forwarding entries in SFF, has been that the information can come 
from a number of places and we do not tie the definitions to the 
mechanisms used to provide them.

As such, I do not understand what form of reference would be 
appropriate, even if the cited document were an active WG document.

Yours,
Joel
