Although tried any modifications described in the "how-to's", I wasn't already able to build up an inheritance using concept of setting superclasses primary-key as primary-and-foreign-key of the subclass. Everything is well functioning, the primitive fields of the superclass are been loaded together with the loaded subclass. BUT reference-descriptors and collection-descriptiors described in the super-class will be ignored, not give damn about them!

Here a look-like :

<class-descriptor class="A" table="A">
        <field-descriptor id="0" name="pk_aid" column="PK_AID" jdbc-type="INTEGER" primarykey="true"
                          autoincrement="true"/>
        <field-descriptor id="1" name="fk_broadid" column="FK_BroadID?" jdbc-type="INTEGER"/>
        <field-descriptor id="2" name="fk_userid" column="FK_UserID?" jdbc-type="INTEGER"/>
        <field-descriptor id="3" name="name" column="Name" jdbc-type="VARCHAR"/>
        <field-descriptor id="4" name="unittyp" column="UnitTyp?" jdbc-type="CHAR"/>
        <!-- begin:references -->
                <reference-descriptor   name="broad" class-ref="Broad"
                                        auto-retrieve="true" auto-update="false" auto-delete="false">
                        <foreignkey field-ref="fk_broadid"/>
                </reference-descriptor>
                <reference-descriptor   name="user" class-ref="User"
                                        auto-retrieve="true" auto-update="false" auto-delete="false">
                        <foreignkey field-ref="fk_userid"/>
                </reference-descriptor>
        <!-- end:references -->
        <!-- begin:collections -->
                <collection-descriptor  name="allCasts" element-class-ref="Cast"
                                        auto-retrieve="true" auto-update="true" auto-delete="true"
                                        orderby="pk_castid" sort="ASC">
                        <inverse-foreignkey field-ref="fk_aid"/>
                </collection-descriptor>
                <collection-descriptor  name="allHistories" element-class-ref="History"
                                        auto-retrieve="true" auto-update="true" auto-delete="true"
                                        orderby="pk_historyid" sort="ASC">
                        <inverse-foreignkey field-ref="fk_aid"/>
                </collection-descriptor>
        <!-- end:collections -->
</class-descriptor>

<class-descriptor class="B" table="B"> 
        <field-descriptor id="0" name="fk_aid" <!-- in RDBMS it is a primary-key and a foreign-key-reference in one -->
                column="FK_AID" jdbc-type="INTEGER" primarykey="true"/>
        <field-descriptor id="1" name="fk_clientid" column="FK_ClientID?" jdbc-type="INTEGER"/>
        <!-- begin:references -->
                <reference-descriptor   name="super" class-ref="A"
                                        auto-retrieve="true" auto-update="true" auto-delete="true">
                        <foreignkey field-ref="fk_aid"/>
                </reference-descriptor>
                <reference-descriptor   name="client" class-ref="Client"
                                        auto-retrieve="true" auto-update="true" auto-delete="true">
                        <foreignkey field-ref="fk_clientid"/>
                </reference-descriptor>
        <!-- end:references -->
</class-descriptor>

Does anyone have any experience with CONCEPT#3 of Inheritance O/R-Mapping ?
