   Preondition Violations

   Type org.eclipse.emf.converter.ModelConverter of variable modelConverter does not match with type org.eclipse.emf.common.util.EMap<java.lang.String,java.lang.String> of variable xMLNSPrefixMap
   - Make classes org.eclipse.emf.converter.ModelConverter and org.eclipse.emf.common.util.EMap extend a common superclass
