/**
 * Tests the extraction of a UML Package into a new sub-model with parallel changes to extracted UML Package.
 * This scenario contains two diagrams, one for the root of the model and another for the extracted package.
 * <dl>
 * <dt>Origin:</dt>
 * <dd>Given is a UML Class Diagram with two classes in the root model, as well as a package with two further
 * classes. We have two diagrams, one showing the root model, the other the contained package.</dd>
 * <dt>Left:</dt>
 * <dd>The contained package is extracted into a new resource named <em>SomePackage</em> (di, uml, and
 * notation). Note that also the diagram showing the extracted package is moved into the resource
 * <em>SomePackage.notation</em>.</dd>
 * <dt>Right:</dt>
 * <dd>The root model undergoes a series of changes, such as a new class <em>Ax</em> is added to the root
 * model, the type of property <em>RootElement/B/a</em> is changed to the new class <em>Ax</em>.</dd>
 * </dl>
