Re: [CCAMP] poll on making draft-zhang-mpls-tp-rsvpte-ext-associated-lsp-04 a WG document

Hi Lou, all,
It would be nice to clarify the scope of the proposed extension. 
I would say (a) if that does not include commitment to work on the "single sided mode". To my current understanding that operation mode is not required for associated bidirectional LSPs. There is no discussion in the document about which operation mode is really needed, if I'm not mistaken similar comments were raised in Beijing, but this is not addressed in the document. Hence my confusion.
Thanks,
Attila

Attila,
	So I appreciate your comment, and would like to have this discussion, but I think I need some clarification from the perspective of the poll.
 I'm unsure if you're saying:
(a) support this document becoming a WG document and would like
    discuss the point raised below in the context of a WG document or
(b) do NOT support this document becoming a WG document until the
    point you raise becomes a WG document

Can you clarify if you mean (a) or (b)?

Lou
