Yaakov,
You've written
This is exactly the point that I've raised in my IETF LC comment on the draft (for MS-PW) - please see my email (to several lists) that explains that in some detail, at
http://www.ietf.org/mail-archive/web/pwe3/current/msg12581.html.
Regards,
Sasha

Was this email meant to address my email to the IETF discussion list (from Tues 16 Aug) or just the discussion on MPLS and PWE lists ?
It does to SOME extent, as it leaves open the possibility of the GAL not being at BoS; but it does not rule out that possibility either.
However, you did not address my other final comment that a PW that starts in an MPLS-TP domain, can easily leak into a non-TP domain. What does one do then ?
(My email also identified a wording issue and what I consider to be a completely inaccurate explanation of what the draft is trying to accomplish.)

======== - Section 4.2. (GAL Applicability and Usage) in [RFC5586], the original text: In MPLS-TP, the GAL MUST be used with packets on a G-ACh on LSPs, Concatenated Segments of LSPs, and with Sections, and MUST NOT be used with PWs. It MUST always be at the bottom of the label stack (i.e., S bit set to 1). However, in other MPLS environments, this document places no restrictions on where the GAL may appear within the label stack or its use with PWs. is replaced by: In MPLS-TP, the GAL MUST be used with packets on a G-ACh on LSPs, Concatenated Segments of LSPs, and with Sections, and MAY be used with PWs. It MUST always be at the bottom of the label stack (i.e., S bit set to 1). However, in other MPLS environments, this document places no restrictions on where the GAL may appear within the label stack. ===== - Section 4.2.
