RTGWG,

There was no comment on this.  The three management requirements below
were added.

Section [?] in the text below is replaced with "Section 4.3" in the
txt version of the draft.

No one so far has offerred a clarification to what was MR#6 which
currently reads "Management Plane SHOULD provide the means for an
operator to initiate an optimization process."
