Well Done, Giuseppe, thanks for taking responsibility to drive this work.
I will send Thursday interim meeting agenda in the separate email.

Hi All,
This is the new version of the draft-ietf-l2sm-l2vpn-service-model.
The most significant changes are reported below (and also summarized in the Appendix A Changes Log section). 
We can discuss them during Thursday interim meeting.

   Changes in v-(01) include:

   o  Reference Update.
   o  Fix figure in section 3.3 and section 3.4;
   o  Consider VPWS, VPLS, EVPN as basic service and view EVC related
      service as additional service;
   o  Add E-Tree as basic service classification together with E-Line
      and E-LAN;
   o  Model structure change, move two customer information related
      parameter into VPN Services container, remove 'customer-info'
   o  Redefine vpn-type to cover VPWS, VPLS, EVPN service;
   o  Consolidate EVC and OVC container, make them optional since for
      some L2VPN service such as EVPN sevice, OVC, EVC are not needed;
   o  Add service and security filter under sites container and change
      "ports" into "site-network-accesses" to get consistent with L3SM
      and also make it generalized;
   o  Fixed usage examples in the l2sm model draft.

Reviews and Comments are welcome

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the L2VPN Service Model of the IETF.

        Title           : A YANG Data Model for L2VPN Service Delivery
        Authors         : Bin Wen

   This document defines a YANG data model that can be used to configure
   a Layer 2 Provider Provisioned VPN service.

   This model is intended to be instantiated at management system to
   deliver the overall service.  This model is not a configuration model
   to be used directly on network elements, but provides an abstracted
   view of the Layer 2 VPN service configuration components.  It is up
   to a management system to take this as an input and generate specific
   configurations models to configure the different network elements to
   deliver the service.  How configuration of network elements is done
   is out of scope of the document.

   The data model in this document includes support for point-to-point
   Virtual Private Wire Services (VPWS) and multipoint Virtual Private
   LAN services (VPLS) that use Pseudowires signaled using the Label
   Distribution Protocol (LDP) and the Border Gateway Protocol (BGP) as
   described in RFC4761 and RFC6624.
