Section: 7

Original Text
-------------
For the ingress node, a Path message with SE style SHOULD also be
sent for decreasing the ODUflex bandwidth.

Corrected Text
--------------
For the ingress node, a Path message with SE style MUST also be
sent for decreasing the ODUflex bandwidth.

Notes
-----
Section 7 requires that Shared Explicit (SE) MUST be used at the beginning when creating a resizable ODUflex connection. Thus, the SE style MUST also be used when signaling for bandwidth increase or decrease.  The increase procedure mandates the use of SE style; however, the decrease procedure uses SHOULD.  The decrease procedure should also make the SE signaling mandatory.

This change, that looks to be a change of substance, has been verified with the authors to be an editorial issue that was caused by not keeping the paragraphs in synch.
