Re: [mpls] working group last call for draft-ietf-mpls-number-0-bw-te-lsps

JP, (co-authors),

         I have some minor questions and some feedback on the 
draft.  See below.

Two questions WRT the above:
- Why are such LSPs excluded from reporting?
- How is the above accomplished for signalled LSPs?

section 3.1:
>    The Number of 0-bandwidth TE LSP(s) sub-TLV is OPTIONAL and MUST
>    appear at most once within [...]
and section 3.2:
>    The Number of 0-bandwidth TE LSP(s) sub-TLV is OPTIONAL and MUST
>    appear at most once within [...]

While your intent is pretty clear, the phrasing is a bit awkward and 
subject to misinterpretation (i.e., what does it mean for an 
"OPTIONAL" element to "MUST" appear ).  How about rephrasing along 
the lines of (change marked in asterisks):

"The Number of 0-bandwidth TE LSP(s) sub-TLV is OPTIONAL and MUST 
***NOT appear more than*** once within [...]"

Should either define or point a reference that defines "a 
dual-thresholds mechanism".

Both suggested values are already assigned.

That's it!
