Why can't we use the pattern in the Data Model Resource book? It's simple and it works.

Yes, this is another good one. This the pattern I had in mind:

     <entity entity-name="PartyClassification" 
package-name="mantle.party.party">
         <field name="partyClassificationId" type="id" is-pk="true"/>
         <field name="classificationTypeEnumId" type="id"/>
         <field name="parentClassificationId" type="id"/>
         <field name="description" type="text-long"/>
         <relationship type="one" title="PartyClassificationType" 
related-entity-name="Enumeration">
             <key-map field-name="classificationTypeEnumId"/>
         </relationship>
         <relationship type="one" title="Parent" 
related-entity-name="PartyClassification">
             <key-map field-name="parentClassificationId"/>
         </relationship>
     </entity>
     <entity entity-name="PartyClassificationAppl" 
package-name="mantle.party.party">
         <field name="partyId" type="id" is-pk="true"/>
         <field name="partyClassificationId" type="id" is-pk="true"/>
         <field name="fromDate" type="date-time" is-pk="true"/>
         <field name="thruDate" type="date-time"/>
         <relationship type="one" related-entity-name="Party"/>
         <relationship type="one" related-entity-name="PartyClassification"/>
     </entity>
