darren hartford commented on ANN-687:
-------------------------------------

Workaround for <id-class...> is through the <attribute-override> tag.

       <id-class class="MyTestId"/>
        <!-- regular column names do not work, 
        so attribute-override (but before attributes elements) -->
        <attribute-override name="compoundOne">
            <column name="COMPOUND_ONE"/>
        </attribute-override>    
        <attribute-override name="compoundTwo">
            <column name="COMPOUND_TWO"/>
        </attribute-override>
        <attributes>
            <id name="compoundOne">
                <column name="COMPOUND_ONE"/>
            </id>
            <id name="compoundTwo">
                <column name="COMPOUND_TWO"/>
            </id> 


No workaround for the many-to-many mapping <join-column>, <inverse-join-column> tags.  Must use the field it expects.

> Use case and urgency of issue related to external technology integration.
> -DTO should not require hibernate-annotations to be used in client-code, but is required when using annotations.  orm.xml approach removes this limitation.
> -GWT 1.4 does not work with java 1.5/annotated DTO.  Although everyone keeps pushing it off saying 'GWT 1.5 is on the way', it is not and solutions that should have been working to work around that limitation need to be working correctly.
