      A natural-language representation for a concept that is both human 
      readable and readable by the Cyc inference engine. These terms are not 
      guaranteed to refer to the same concept across time but are guaranteed to
      be consistent within a particular OWL export. Use 'cycAnnot:externalID'
      for unambiguously referring to a concept across OWL exports or across Cyc
      inference engines.
