Re: [DMM] New Version Notification for draft-clt-dmm-tn-aware-mobility-07.txt

["Joel M. Halpern" <[e-mail]>]

I would note that it seems a little odd to do this work when we do not 
have agreement on what the exposed properties are of an IETF Network 
Slice (see the TEAS discussion), much less how packets are mapped to them.

Yours,
Joel
