      DEFINITION
         The DEFINITION relationship identifies a definition of a term.

         Definitions may be, but are not necessarily, contained within a
         glossary.  DEFINITION would most typically be specified on an A
         element, as it would specify a hypertext link from a term to
         its definition.
