When is a document not a Document but still a document?

Documents have a bad perception, they are big, unfocused, and hard to process or view. I'm going to propose something that is counter to the perception, driven by current healthcare use of CDA documents and the HL7 Principles of a Document. Something supported by IHE Document Sharing (XDS/XDR/XDM/XCA/MHD), something enabled and using #FHIR.When is a Document a Document?Some background that is important can be found in the IHE HIE-Witepaper in the section on "Principles of IHE for Health Document Sharing"....
