[Moims-dai] Suggested changes to fix Packaging inconsistency

[Mark Conrad]

David,

I strongly disagree with your suggested changes. The OAIS preserves AIPs
consisting of Content Information and PDI. SIPs may contain parts of the
Content Info and/or PDI needed to create the AIPs. DIPs can contain any
type of Information that the OAIS chooses to deliver. The inconsistency is
in how an Information Package is defined. SIPs, AIPs, and DIPs can have
drastically different content and are used for very different purposes. The
current definition of an Information Package does not reflect this
diversity.
