org.eclipse.sirius.viewpoint.DSemanticDecorator.getTarget() in a Java
service or the target EReference in an Acceleo expression should solve
your problem
[yourExpressionToTheDiagram.oclAsType(DSemanticDecorator).target/] and
return the domain EObject. DDiagramElement inherits from
DSemanticDecorator and so does DSemanticDiagram which should be the
EClass of your current "root graphical elemet of the diagram".
