Resolved all remaining issues with OAIS update.

6. DAI WG REPORT CROSS-AREA TECHNICAL ISSUES
Issue 1 Concern that Magenta Books could run into problems in transition to ISO Standard. No Magenta Book has been approved as an ISO Standard (1 has been submitted).
Issue 2 OAIS Issue 2 should remain a CCSDS Standard (Blue Book)
Change of color will be confusing to community (largest for any CCSDS document)
Change of color will likely be seen by the community as a demotion
Change of color could result in renumbering by ISO.
Renumbering would cause confusion in the community and would result in inconsistent use of new and old standard.
Renumbering would dilute effectiveness of previous efforts to ensure community acceptance and use of standard.
Such changes could diminish the image of CCSDS in the wider community.

7. DAI WG REPORT CROSS-AREA TECHNICAL ISSUES (from previous meetings)
Issue 1 CESG/CMC should investigate additional sources for determining requirements and priorities for Archiving.
IOAG is primarily oriented to communications and has little interest or expertise in Archiving areas
Issue 2 Our CCSDS Standards (which specify registries, e.g. ADIDs) also become ISO standards. We want a single registry of all registered items that is respected by and used by entire community (both CCSDS and ISO outside of CCSDS).
If needed for community acceptance, separate Maintenance Agencies (MAs) (outside CCSDS) should be allowed.
If a separate MA for registry is specified, then CCSDS SANA should point to it appropriately.
If SANA handles the registry, should support mechanism for supporting registrations from outside CCSDS Members.
