Drop the mandatory field ACCESS TYPE CODE from MLPRevisionDescription
At present a modeler may attach TWO different descriptions to a SINGLE published model, one at the "company" visibility level and one at the "public" visibility level. This feature is not clear to users and has caused problems; for example see ACUMOS-2459 and
ACUMOS-2460. This feature is meaningless when users will publish to catalogs.
This is a disruptive change and needs some discussion.
