/**
 * A package is a grouping of model elements.
 *
 *
 *
 * In the metamodel, Package is a subclass of Namespace. A Package contains
 * ModelElements such as Packages and Classifiers. A Package may also contain
 * Constraints and Dependencies between ModelElements of the Package.
 *
 *
 *
 * The purpose of the package construct is to provide a general grouping
 * mechanism. In fact, its only semantics is to define a namespace for its
 * contents. The package construct can be used for organizing elements for any
 * purpose; the criteria to use for grouping elements together into one package
 * are not defined.
 *
 *
 *
 * A package owns a set of model elements, with the implication that if the
 * package is removed from the model, so are the elements owned by the package.
 * Elements with names, such as classifiers, that are owned by the same package
 * must have unique names within the package, although elements in different
 * packages may have the same name.
 *
 *
 *
 * There may be relationships between elements contained in the same package, and
 * between an element in one package and an element in a surrounding package at
 * any level. In other words, elements ?see? all the way out through nested levels
 * of packages.
 *
 *
 *
 * Elements in peer packages, however, are encapsulated and are not a priori
 * visible to each other. The same goes for elements in contained packages, i.e.
 * packages do not see "inwards".
 *
 *
 *
 * Elements owned by a Package can be made available to other Packages by importing
 *
 * them. Although any ModelElement may be imported by a Package, imported
 *
 * ModelElements are typically other Packages. When an element is imported by a
 *
 * package it extends the namespace of that package. Thus the elements available
 * in a
 *
 * Package consists of its owned and imported ModelElements.
