   * KB comment for #$CycLOpenDenotationalTerm as of 2002/05/07:<p>
   *
   * The collection of all open denotational terms in the CycL language.  An
   * expression is "open" if it contains one or more free variables (see
   * #$CycLOpenExpression).  A CycL term is said to be "denotational" if it is the
   * right sort of term to have a denotation (or value) in the universe of
   * discourse (see #$CycLDenotationalTerm).  Each instance of
   * #$CycLOpenDenotationalTerm is either a #$CycLOpenNonAtomicTerm (i.e. a "NAT"
   * with a free variable) or a #$CycLVariable iself.  Examples include `?X',
   * `(#$JuvenileFn ?X)', and `(#$JuvenileFn #$isa ?X #$genls #$JuvenileFn)' (even
   * though the latter is semantically ill-formed).<p>
