An <code>AmaltheaCrossReferenceAdapter</code> is created and attached to the root context of the model.
The adapter maintains an index that allows fast access to inverse references and an index based on object name.

The method <a href="#getInverseReferences-org.eclipse.emf.ecore.EObject-org.eclipse.emf.ecore.EReference-java.util.Set-"><code>getInverseReferences</code></a> is called from several
