Re: [Teas] Disposition of draft-ietf-teas-ietf-network-slice-definition-00

[Greg Mirsky <[e-mail]>]

Hi John, Eric, et al.,
I appreciate the proposal and believe that it correctly reflects the
discussion of the draft-ietf-teas-network-slice-definition we had within
the DT and as the WG. In fact, I support the proposed updates of the
content of the draft-ietf-teas-network-slice-definition while maintaining
it as a separate document. In my opinion, either way, works.

Regards,
Greg
