Identifying limitations
=======================

            Compared to building a hypertext system that properly
Careful     classifies a wide range of advice, identifying when the
<jump>      contained insights are inappropriate is perhaps the developers
            most difficult step.

            Normally, it takes years of experience to understand the boundaries
            or limitations in any knowledge.  With practice, most hypertext
Exception   developers can add reasonable properties of ACCESS, RELATIONSHIP,
<jump>      and EXAMPLE to subjects outside of their initial understanding.

            The best way to add LIMITATIONS to a hypertext system is to
            save that for the last step.  Find the person most expert on
Not true    the contained subject, then physically go through all the source
<jump>      material screen to identify exceptions (using margin jumps) to
            the contained advice.

            From a classical viewpoint, the value added to information by
            hypertext is ACCESS, RELATIONSHIP, EXAMPLE, BOUNDARY, and
            VOCABULARY.  When these properties are all present, persons
            unfamiliar with the subject can rapidly acquire understanding.
