    NAME:
    Initial DD42 Schema Development
    
    DESCRIPTION:
    Develop W3C XML Schema to define class of instance documents which will
    functionally replace on existing paper document, the DD42.
    This is a particular version of the DD42.
    
    PRECONDITIONS:
    1. 'Have existing paper-based design documents.
    2. 'Have access to people who know how the paper document is actually
       used.
    
    PROCEDURE:
    1. Build a graphical Semantic Diagram (UML class diagram) model of the
       paper DD42.
    2. Circulate it among actual users of the paper document and add all of
       the non-standard usages, quirks, and imponderables they raise to the
       extent possible.
    3. Decide which variations thus uncovered will be supported in detail by
       the electronic version of the document, and which will have to go in
       a comments field or some-such.
    4. Generate a corrected graphical Semantic Diagram model of the paper
       document as it is actually used.
    5. Compare data component requirements shown by Semantic Diagram, with
       the CC catalog.
    6. Construct any new CC's which are required
    7. Build a graphical Schema Diagram (UML class diagram) model for the
       DD42.
