The Relationship Mbr Options clause allows you to specify a
    relationship member. This member can be an existing element in
    the repository, or it can be an element you create within the
    DEFINE GENERIC Relationship Member Options clause.

    To specify an existing element as a relationship member, include
    only the element's name in the Relationship Member Options
    clause. To define a new element as a relationship member, specify
    the Generic clause within the Relationship Member Options clause.

    The Generic clause does not create directory names for
    relationship members. Without a directory name, you cannot
    display elements with the DIRECTORY command or include element
    definitions in other definitions.

    To display relationship members, issue the SHOW GENERIC command
    with the /FULL qualifier. To provide a directory name for a
    relationship member, issue the ENTER command.

    If you use the Generic clause, you can nest a series of
    relationship members.
