I define two XML type (base and derived types).

 <xs:complexType name="ParentType">
   ...
 </xs:complexType>

 <xs:complexType name="ChildType">
  <xs:complexContent>
  <xs:extension base="ParentType">
   ...
  </xs:complexContent>
 </xs:complexType> 

Now, I have an XML instance of ChildType. The question, If I once unmarshall the XML into ParentType java object, can I downcast the java object to its subclass of ChildType?

Is that possible to that?

thanks
