Hi All,
This is the new version of the draft-ietf-l2sm-l2vpn-service-model.
It addresses some comments from people that are trying to implement the draft and it includes also an update to the references in particular to RFC8199 and RFC8309.
As usual, the fundamental changes are summarized in the Appendix A "Changes Log":

   Changes in v-(05) include:

   o  Change type from 16-bit integer to string for the leaf id under
      "qos-classification-policy" container.

   o  Stick to using ordered-by user and remove inefficiency to map
      service model sequence number to device model sequence number.

   o  Remove mandating the use of deviations and add "if-feature target-
      sites" under the leaf-list target-sites in section 5.10.2.

   o  RFC2119 language changes on operation of the management system in
      Section 5.6,3rd paragraph and section 7.

   o  Fix incomplete description statements.

   o  Change the use of the absolute paths to the use of relative paths
      in the "must" statement or "path" statement for vpn-policy-id leaf
      node, management container, location leaf node, devices container,
      location case, location-reference leaf, device case, device-
      reference leaf to make configuration is only applicable to the
      current sites.

   o  Change "must" statement to "when" statement for management
      container device container.

   o  Define new grouping vpn-profile-cfg for all the identifiers
      provided by SP to the customer.  The identifiers include cloud-
      identifier, std-qos-profile.

   o  Add in the XPATH string representation and remove unqualified

   o  Remove redundant parameters in the cloud access.

   o  Add a few text to clarify what the site is in section 6.3.

   o  Add multi-filter and multi-VPN per entry support for VPN policy.

   o  Modify description for svc-bandwidth leaf to make it consistent
      with the text in section 5.10.1.

   o  Add text to clarify the way to achieve Per-VPN QoS policy.

   o  Change guaranteed-bw-percent data type from uint8 to decimal64.

Reviews and Comments are always welcome.

Best Regards,

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