      END or LAST
         The END relationship identifies the author defined end of a
         sequence of documents of which the current document is a node.
         TOP is a functional equivalent to END when only one is
         specified.

         When REL=END, the target document is the end of the sequence.
         When REV=END, the current document is the end of the sequence.

         If the hypertext link is specified with REL in a LINK element,
         an HTML user agent may present an icon in a tool bar.
