Thanks for this new revision, authors.

Looking at the diff, I see that the main differences are

1. Add usage example in section 7
2. Change the model structure to be more in line with the L3SM model
3. Adjust the model to put service requirements in the top level so that they
can be easily described using XML snippets in section 7
4. Addition of "cloud-access" as a mode of VPN
5. Fill in a few cases of "TBD" in the description of the module

I also see quite a few places where the text has been cleaned up, but they don't
make a substantial difference to the document (except for making it easier to

The question for the WG is:

Are there any remaining reservations about using this document as a starting
point for IETF work to meet the WG objectives? That question is not "is this
document perfect?" but we are asking whether the WG thinks it would be
impossible to bend this document to meet the WG deliverables.

If there are no more objections (oh, and feel free to express your support!) we
can move forward and start the hard work.

> 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 use 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.
