All Sirius model elements which represent a semantic/domain element
implement the org.eclipse.sirius.viewpoint.DSemanticDecorator interface,
which provides the getTarget() method (actually an EMF EReference) to
access the underlying EObject.

This is the case for:
* all "top-level" representations (diagrams, which in practice are
instances of DSemanticDiagram that inherit from DDiagram; tables,
instances of DTable; and trees, instances of DTree);
* all the individual elements (DRepresentationElement) inside these
representations: DNodes/DContainer/DEdges/etc. in diagrams,
DLine/DColumn in tables, and DTreeItem in tree representations.
DRepresentationElement also provides getSemanticElements() to access the
"secondary" associated semantic elements, if any (the ones specified via
"Associated Elements Expressions" in the mapping definitions).
