An EDataType is a thing from the Ecore model and generally an EDataType
is an EClassifier so we would expect such an EClassifier is contained by
an EPackage's getEClassifiers. An EClassifier that isn't contained by
an EPackage doesn't have much meaning, i.e., we can't figure out what
factory would be used for converting values to and from a string the way
EcoreUtil.convertToString/createFromString would normally do it.
