== COMMENTS ==

-- Section 4.2.2.1 --
May be am I failing to understand this part of the sentence "|X| is the minimum
value from 0 to max(P, Q)" as it is not the same as "where -P <= X <= Q" or
does the "|X|" not represent the absolute value of X ?

[HC]: "|X|" represents the absolute value of X.
There are two sentences:
1) "[Ta, Tb] within -P and Q" means a time period from (Ta+X) to (Tb+X),
   where -P <= X <= Q.
2) When an LSP is configured with elastic time interval "[Ta, Tb] within
   -P and Q", a path is computed such that the path satisfies the
   constraints for the LSP in the time period from (Ta+X) to (Tb+X)
   and |X| is the minimum value from 0 to max(P, Q).
In the first sentence, an acceptable range of X is given by -P <= X <= Q.
In the second sentence, a value of X is found within the acceptable range
to satisfies the constraints.
If we change X to Xv in the second sentence, it may be clear.
2)' When an LSP is configured with elastic time interval "[Ta, Tb] within
   -P and Q", a path is computed such that the path satisfies the
   constraints for the LSP in the time period from (Ta+Xv) to (Tb+Xv)
   and |Xv| is the minimum value for Vx from -P to Q.
We have rephrased the related text in the updated document.

== NITS ==

-- Section 4.2.2.1 --
Please use "are" rather than "is" in "Note that both Ta and Tb is shifted by
the same 'X'"

[HC]: We have changed "is" to "are".
