Hi Adrian,

A few comments:

  * The most relevant part of the MEF work in progress (i.e. the working
    drafts of their Yang modules) was attached to the liaison rather
    than being available via the login; so prob need to tweak the
    wording a bit to thank them for that as well.
  * Their liaison asked a for a specific clarification with respect to
    the charter; it would be helpful to provide the clarification  in
    the reply.
  * They also suggest that L2SM proceeds by augmenting the MEF modules -
    it might be useful to address that point specifically in the reply
    (even if it's only to say that no decision has yet been reached by
    the WG).


Thanks,

     David
