Everything is either an Individual or a Class.
Property is a Class, and it is the property which all properties are subproperties of.

  Of course you're right again.   I give up.   :-)    (I really
  shouldn't try to do think when I'm sitting in meetings.)

  (Is there a name for the Property which all Properties are

  but is it defined as something?)
