Hi Adrian,

One point that I would like to raise is that it would be important to describe the relationship between this work and what is happening at other standardization bodies such as the MEF Legato YANG service modules and the TAPI work at the ONF.


Ref MEF Legato YANG modules:

    We're approaching Working Groups last call on our draft.
    - I have requested a YANG Doctor review of the current revision
    - I plan to do an English language review at the same time (unless
       someone else want to volunteer)
    - NOW is the time for you to do your technical review. Don't leave
       is until WG last call!
    - All things being equal, we will have WG last call in early February

    > Abstract:
    >    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
