/**
 * Tests the re-integration of a UML Package from a sub-model with parallel addition of an element to
 * re-integrated UML Package. This scenario <em>does not</em> contain two diagrams (in contrast to
 * {@link ResourceAttachmentChangeDelete1GitMergeTest}), but only one which is located in
 * <em>model.notation</em>.
 * <dl>
 * <dt>Origin:</dt>
 * <dd>Given is a UML Class Diagram that refers to an extracted UML Package contained in the resource
 * <em>Package1.uml</em>, which in turn contains one class. We have only one diagram, which is contained in
 * <em>model.notation</em>.</dd>
 * <dt>Left:</dt>
 * <dd>A second class is added to the extracted package in <em>Package1.uml</em> . Also a shape is added to
 * the diagram in <em>model.notation</em>.</dd>
 * <dt>Right:</dt>
 * <dd>The extracted package <em>Package1</em> (di, notation, and uml) is re-integrated into <em>model</em>
 * (di, notation, and uml).</dd>
