<p class=MsoNormal style='margin-left:.5in'>Also, for reference, is the latest
concept paper. I do not believe that this will be completed before the
May. Therefore, I believe it would be most beneficial for the BOF to
focus on presentation of the concept developed to date for a wider CCSDS
audience to help shape the forward work after the May meetings.
I think that construction of a view based on a viewpoint specification as
an example would be a very worthy accomplishment by the time of the May
meetings. <o:p></o:p></p>
