4. Document LifeCycle Management Document Set Id shall be under the control of the Source of Original Version number is an optional/unused field (policy to increment ?) Addendum and Original Registry Entries shall be similar. Consumer may always find all original and addendum by Doc SetId. Document Addendum Document 1 (Available) Doc Set Id Parent Id Replacement Document Parent Id Document 1 (Deprecated) Doc Set Id Document 2 (transform) Parent Id Document 1 Doc Set Id Replacement doc and availability status change shall be part of the same submission set. A transformed document may be part of the same submission set or not. Only way to find if a document has transforms is to query using SetId.

Re-Submission Goal is to detect and solve re-submission when happen Suggest making this detection and correction an option New Doc Submission Set New Doc A Submission Set (Reqested) New Doc New Doc A Registry/Repository detects re-submission Prev Doc Submission Set (Registered) New Doc Alternatives ? Multiple Registry Entry/Doc with same UID confuses Consumer One Registry Entry with multiple Docs complex, not useful for Consumer, and likelihood of exact same Registry Entry with same Doc UID+Hash in re-submission is small.
