COMMENT:
----------------------------------------------------------------------

I was not sure how this behavior in Section 8 is expected to be deployed and
used.

"  A DS domain that still uses DSCP CS1 for marking LE traffic
   (including Low Priority-Data as defined in [RFC4594] or the old
   definition in [RFC3662]) SHOULD remark traffic to the LE DSCP
   '000001' at the egress to the next DS domain."

Is the expectation that even on a domain that has not been updated to use the
new DSCP there will be some node at the edge that will have been updated? If
so, it might be good to explicitly note this. If not, I cannot see how a legacy
node will follow this recommendation.
