/**
 * Tests loading of models when an emf model extension is missing.
 * <p/>
 * Expected behavior is for model to load all entities and traits even if extension model is not
 * loaded.   The trait values will be missing where the trait value model is missing.  
 * In these cases, an error should be logged to the JSFCommonPlugin.
 * <p>
 * 
 * <p/>
 * Note: if xsi:type prefix is bad, or no uri to model was provided, then model will NOT load.   
 * This JUnit does not test for the model not loading in this case.
