    I think you mean "separating".

    Can you give a short example that shows one or more of these, and how
    they would work together? What are narrative, reference, and graphic
    control semantic information, anyway? What happens when you change one
    set of external links? For example if you change the organization, what
    happens to to the others?

    How can that be done? How does the system know when I add a new word
    whether it is part of a heading or the paragraph that follows it. Or
    whether it is inside or outside of a bolded section. There must be
    dozens of "end points" for which the proper location for an insertion is
