Re: [OPSAWG] AD review of draft-ietf-opsawg-sap-09

[[e-mail]]

Hi Tom, all,

We already have the following in the Introduction: 

   A network may support multiple services, potentially of different
   types.  Whether a SAP topology is dedicated to services of a specific
   service type, an individual service, or shared among many services of
   different types is deployment specific.  This document supports all
   of these deployment schemes.

Added this NEW text to the Abstract: 

 One or multiple services can be bound to the same SAP.

Thanks.

Cheers,
Med
