code: protected boolean isPotentialLazyCrossReference(EStructuralFeature feature) {
  		return !feature.isDerived() && !feature.isTransient() 
  				&& feature instanceof EReference && ((EReference)feature).isResolveProxies();
  	}
docs: Return <code>true</code> if the given feature may hold a proxy that has to be resolved.
  
  This is supposed to be an internal hook which allows to resolve proxies even in cases
  where EMF prohibits proxies, e.g. in case of opposite references.
