List.identifier should differentiate SubmissionSet.entryUUID and SubmissionSet.uniqueId

Issue
identifier is mapped to SubmissionSet.entryUUID and SubmissionSet.uniqueId

it is not clear how the identifier should be mapped to entryUUID or uniqueId, it could be differentiated by oid/uuid but this seems not obvious.

Proposed Change

For MHD Rev. 3.2 – 2020-08-28 it was specified for Folder that "When the List.identifier carries the entryUUID, then the List.identifier.use shall be ‘official’. When the List.identifier carries the uniqueId, then the List.identifier.use shall be ‘usual’.", I propose this concept should be incorporated in the MHD List profile for Folder and SubmissionSet.

Priority:

• Medium: Significant issue or clarification. Requires discussion, but should not lead to long debate.

thanks. Good solution. I don't think we can demand cardinality as your pull-request does. but the slicing pattern is good. Likely need narrative too.
