Yes.  I did simplify my description.  Each Cyc #$Microtheory (context)
may have a set of assertions that help define that context.  This is
the proper place for defining (or referencing) individuals (such as the
Sun or specific #$GeopoliticalEntity) which are special to that context.
Such individuals are expected to be used within the context.  However,
when Cyc moved all basic definitional vocabulary terms to the
#$UniversalVocabularyMt such linkages got lost.    (04)

If we did create theory contexts, we would want to allow individuals
which are critical to the specific theories in the context, and to
designate them as such.    (07)
