[PWE3] BFD for MPLS PWs

Rahul, 

At the PWE session you stated that the MPLS BFD draft
described the use of BFD for PWs, and that the VCCV draft
and the BFD MPLS draft need to remain aligned.

The only mention I find in draft draft-ietf-bfd-mpls-03.txt of PWs
is the following motivational text:

   2. MPLS Pseudo Wires (PW). Fast detection may be desired for MPLS
   PWs depending on i) the model used to layer the MPLS network with the
   layer 2 network. and ii) the service that the PW is emulating. For a
   non-overlay model between the layer 2 network and the MPLS network
   the provider may rely on PW fault detection to provide service status
   to the end-systems. Also in that case interworking scenarios such as
   ATM/Frame Relay interworking may force periodic PW fault detection
   messages. Depending on the requirements of the service that the MPLS
   PW is emulating, fast failure detection may be desirable. Use of BFD
   for PWs is further described in [VCCV] and [OAM-MAP].

I don't see any normative text here, and certainly nothing describing
whether or not UDP is used. What I do see is a pointer to VCCV,
so that any changes in VCCV should reflect here.

Section 4 on "theory of operation" seems to be silent on PW issues.

Am I missing something?
