/**
 * A namespace is a part of a model that contains a set of ModelElements each of
 * whose
 *
 * names designates a unique element within the namespace.
 *
 *
 *
 * In the metamodel, a Namespace is a ModelElement that can own other
 * ModelElements, such as Classifiers. The name of each owned ModelElement must be
 * unique within the Namespace. Moreover, each contained ModelElement is owned by
 * at most one Namespace. The concrete subclasses of Namespace may have additional
 * constraints on which kind of elements may be contained.
 *
 *
 *
 * Namespace is an abstract metaclass.
 *
 *
 *
 * Note that explicit parts of a model element, such as the features of a
 * Classifier, are not modeled as owned elements in a namespace. A namespace is
 * used for unstructured contents such as the contents of a  package, or a class
 * declared inside the scope of another class.
