    Review of Atlantic call minutes of 2011.01.05

       GKH: Andrea reports that Security SC has approved the latest
       changes.  JB has now been given all the expected text.  SGTG
       will put revised schemas through our acceptance process as
       soon as eDoCreator has been updated with the changes for
       PRD2 (still undergoing review in PSC and TSC).  All text
       deliverables from GKH are now complete.  Question: will the
       Security SC document itself be part of the 2.1 package?

       JB: That is currently the plan of record, but will consider
       this again for next week's call.

UBL 2.1 STATUS

    TM: PSC meets today to finalize three of the five remaining
    issues.  TSC will probably meet Friday.

MESSAGE ENVELOPE

    High points of the discussion:

     - A primary use case is the envelope for tender submissions.

     - AH reports that the OASIS Energy Market Information Exchange
       (eMIX) TC has identified a similar need for a document
       containing a bundle of documents (e.g., associated warrants
       or energy certificates), each with its own metadata,
       together with a requirement to identify one of the documents
       in the bundle as primary.

     - Sweden has confirmed the BII finding that UN/CEFACT SBDH 1.3
       will not, in fact, support a bundle of document instances in
       a single envelope in a way that meets BII business
       requirements.

     - AH reports that Stephen Green independently attempted an
       implementation of SBDH and had to abandon it because of this
       limitation.  Stephen has identified use cases with multiple
       documents of different types in the same bundle or even the
       inclusion of non-UBL documents, e.g., the inclusion of an
       XBRL-GL ledger instance.

     - It appears that GS1 has had to make its own adaptations to
       the SBDH, presumably for the same reason.

     - It is our independent finding that the SBDH as currently
       specified (xsd:any without maxoccurs unbounded) cannot
       support multiple document roots as siblings if metadata is
       associated with each document.  This problem could be solved
       by setting maxoccurs to unbounded, but apparently there are
       other business requirements that this solution would not
       address; we are seeking further clarification from BII on
       this point.

          ACTION: TM to provide a snapshot of the BII model (with
          the understanding that this is a work in progress).
