Hi Benoît, 

A candidate version that takes into account your comment can be seen at: https://github.com/IETF-OPSAWG-WG/lxnm/blob/master/I-D-sap/draft-ietf-opsawg-sap.txt 

As a reminder, your previous comments were: 

==
 * Do we want to say that there are existing SAPs on PE routers, to which we can deploy new services?
 * Or do we want to say there is an existing service that connects CE2 to a specific SAP on PE2?
==

The candidate version clarifies the intended usage. It basically covers both cases listed (and more) with companion illustration examples (see the appendices). In particular, the module can expose interfaces that are ready to "host" service-specific interfaces, a list of instantiated (active) SAPs, etc. The "sap-status" and "service-status" attributes reflect the actual status of the SAP/service. Both attributes are needed as the same SAP may be used for multiple services. For active SAPs, a peer endpoint identifier can also be retrieved. This is particularly useful for binding a service request to the network view. Also, SAPs can be filtered per service type. 

Please let us know if you have any further comments.  

Thank you. 

Cheers, 
Med
