Small issue on draft-ietf-ccamp-gmpls-sdh-00.txt

["Bernstein, Greg" <GregB@ciena.com>]

Hi in the draft draft-ietf-ccamp-gmpls-sdh-00.txt it says:

   In case of any type of contiguous concatenation (e.g. standard or
   arbitrary concatenation), only one label appears in the Label
   field. That label is the lowest signal of the contiguously
   concatenated signal. By lowest signal we mean the one having the
   lowest label when compared as integer values, i.e. the first
   component signal of the concatenated signal encountered when
   descending the tree.

   In case of virtual concatenation, the explicit ordered list of all
   labels in the concatenation is given. Each label indicates a
   component of the virtually concatenated signal.

This does not reflect the intent of arbitrary concatenation- arbitrary, size
and placement of timeslots.  Otherwise the main benefit of arbitrary
concatenation, preventing re-grooming is lost.  Corrected text could read:

    In the case of standard contiguous, only one label appears in the Label
   field. That label is the lowest signal of the standard contiguously
   concatenated signal. By lowest signal we mean the one having the
   lowest label when compared as integer values, i.e. the first
   component signal of the concatenated signal encountered when
   descending the tree.

   In the cases of arbitrary or virtual concatenation, the explicit ordered
list of all
   labels in the concatenation is given. Each label indicates a
   component of the arbitrary or virtually concatenated signal.
