    There is no explicit mapping of abstract entities via the Modeler.
    Instead you'd specify a custom superclass for each individual entity
    (see "Superclass" field in the ObjEntity Editor in the Modeler) or
    for all entities at once (see "Custom Superclass" field in the
    DataMap Editor panel).
