Work Item 23
Business document and envelope with more than one document*
*
Description: Investigate how to handle a business document and envelope 
with more than one structured document.

Related work items: 25 and 32

Summary proposal based on Roberts proposal and F2F discussion/followup:

    * Provide the same structure for the attachment as the business
      document.
          o Additional function: Propose to add a flag indicating that
            an attachment is required or not.
    * Provide additional capability to identify a document.
          o Reason: The v1.01 schema has the specificationLocation and
            specificationID and a ConditionExpression which allows for
            both a reference to a 'schema' describing the document and a
            simple method for any BPSS engine to identify the document.
            The 'schema' is not necessarily an XML schema but any
            mechanism that can be used to describe the contents of the
            business document. This could be used by any validation
            engine in deployment.
          o Additional function: Add an extra optional parameter called
            specificationType that would be used to indicate what type
            of specification the document is expressed in, e.g. XSD,
            RNG, CAM or any other useful tool. This is optional because
            the BPSS should be able to refer to a document as a logical
            item with no 'specification..' information until a later
            binding is applied.

Open items:

    * Determine if attachments are first-class documents.
          o Are they included?
          o Are they required?
          o If first class elements, can they affect the business
            process? In February, we indicated they do not. Ask for more
            information from CPPA Negotiation team regarding use of
            draft CPA, Negotiation message and Negotiation Descriptor
            Document (NDD).
    * Would this require a WSDL definition for attachments?

Martin has integrated some of the attachment structure in his 1 March 
schema post I believe:
