Binding compiler should check for class assignability instead of exact type.

Binding compiler should check for class assignability instead of exact type name matching between structure type and mapping class. In the mapping:

<structure field="..." type="ParentType"/>
<mapping name="child1" type="Child1" ...>...</mapping>
<mapping name="child2" type="Child2" ...>...</mapping>
.
.
.
the compiler generates error. I workaround this by using custom un/marshaller for structure:

public class ConfigHandler implements IMarshaller, IUnmarshaller{
protected String uri="http://www.datalan.sk/search/robot-config/1.1";
public boolean isExtension(int index)

{ return false; }

public void marshal(Object obj, IMarshallingContext ictx) throws JiBXException

{ if(!(ictx instanceof MarshallingContext)) throw new JiBXException("Invalid object type for marshaller"); ((IMarshallable)obj).marshal(ictx); }

public boolean isPresent(IUnmarshallingContext ctx) throws JiBXException

{ return ctx.isAt(uri, "processing-option")||ctx.isAt(uri, "processing-chain")||ctx.isAt(uri, "processor"); }

public Object unmarshal(Object obj, IUnmarshallingContext ctx) throws JiBXException

{ return ctx.unmarshalElement(); }

} // end of type

Even though the un/marshaller is that trivial, (or perhaps because of it) the behaviour should be implemented directly by JiBX.
