My ecore model has reference to an interface, which is implemented by two concrete objects. Here are parts of model in question:

  <eClassifiers xsi:type="ecore:EClass" name="Zoo">
    <eStructuralFeatures xsi:type="ecore:EReference" name="animal" upperBound="-1"
        eType="#//Animal" containment="true"/>
  </eClassifiers>
...
...
  <eClassifiers xsi:type="ecore:EClass" name="Lion" eSuperTypes="#//Animal"/>
  <eClassifiers xsi:type="ecore:EClass" name="Monkey" eSuperTypes="#//Animal">


When I add a Lion to my model: Zoo.getAnimal().add(Lion) and Zoo.getAnimal().add(Monkey) the model is serialized as follows:

<bdi:Zoo>
     <animal xsi:type="bdi:Lion"/>
    <animal xsi:type="bdi:Monkey"/>
</bdi:Zoo>


Is it possible to persist model so that I don't get type generated for animal element, but instead concrete type is serialized:

<bdi:Zoo>
     <Lion/>
    <Monkey/>
</bdi:Zoo>


Thanks,
Alex

With a great deal of effort and all kinds of magical extended metadata annotations along with a messier model API you could achieve something like this as describe in this old blog:
