<!--                      The attribute "refloc" is used to point to
                          the ID of the item being referenced.
                          The attribute "type" specifies the type
                          of the cross reference.  TYPE="number"
                          generates the number of the referenced
                          element (if it is numbered, and the
                          result is undefined for references to
                          elements that are not numbered).  For
                          example, 'See figure <xref type="number"
                          refloc="fg0001">' would be formatted as
                          'See figure 2'.
                          TYPE="title" generates the title of the
                          referenced element (if it does contain
                          a title element, and the result is
                          undefined for references to elements
                          that do not contain titles).  For
                          example, 'See the section "<xref
                          type="title" refloc="sec02">"' would be
                          formatted as 'See the section "Using
                          Cross References"'.                   -->
