 * @since J2EE1.3 The ejb-relationship-role element describes a role within a
 * relationship. There are two roles in each relationship. The
 * ejb-relationship-role element contains an optional description; an
 * optional name for the relationship role; a specification of the
 * multiplicity of the role; an optional specification of cascade-delete
 * functionality for the role; the role source; and a declaration of the
 * cmr-field, if any, by means of which the other side of the
 * relationship is accessed from the perspective of the role source. The
 * multiplicity and relationship-role-source element are mandatory. The
 * relationship-role-source element designates an entity-bean by means of
 * an ejb-name element. For bidirectional relationships, both roles of a
 * relationship must declare a relationship-role-source element that
 * specifies a cmr-field in terms of which the relationship is accessed.
 * The lack of a cmr-field element in an ejb-relationship-role specifies
 * that the relationship is unidirectional in navigability and that
 * entity bean that participates in the relationship is "not aware" of
 * the relationship.
