I've not actually done this but I imagine that it would be fairly
easy. Just have each class map to different fields in the table.

This is completely contrived but I believe a mapping descriptor
might look like this:

<class name="Parent" identity="id">
    <map-to table="person_info" />
    <field name="id" type="big-decimal">
        <sql name="parent_id" type="decimal" />
    </field>
    <field name="surName" type="string">
        <sql name="sur_name" type="varchar2" />
    </field>
    <field name="givenName" type="string">
        <sql name="given_name" type="varchar2" />
    </field>
</class>

<class name="Child" identity="id">
    <map-to table="person_info" />
    <field name="id" type="big-decimal">
        <sql name="child_id" type="decimal" />
    </field>
    <field name="address" type="string">
        <sql name="address" type="varchar2" />
    </field>
    <field name="city" type="string">
        <sql name="city" type="varchar2" />
    </field>
</class>

Can anyone confirm or deny whether my example might work?
