Inheritance with extra columns.

[Owens, Ryan]

I've seen a few similar questions a little while ago but no responses, sorry if I 
missed something.

I'm trying to do some inheritance between tables and from what I've read and tried so 
far it seems that the default inheritance model in torque won't let me add new columns 
to 'subclasses' of another table. So far all 

For instance, this schema:

<table name "test">     <column
         name="id"
         required="true"
         primaryKey="true"
         type="INTEGER"
             />
             
     <column name="inheritance" inheritance="single"
         type="CHAR">
         <inheritance class="Foo"
             extends="com.test.om.Test"
             key="A"
             />
         <inheritance class="Bar"
             extends="com.test.om.Test"
             key="B"
             />

     </column>
