BPMN11 — UML class diagram in the appendix

The UML class diagram in the appendix as revised after Ballot 4, is an object model, and it should not be an object model .

More particularly, the new diagram in Appendix B looks like a metamodel for BPMN Element, In particular, it seems to show abstract classes (using italics for names),
shows visibility public '+' for attributes, shows generalization relationships,
and uses the notation for representing classes (or metaclasses), and attributes.

This is misleading at best. It is understood within the FTF that the intent was to show the tables in a concise form,
by using generalization to represent relationships among the tables in the appendix, but the diagram as it stands does not do that, since it includes concepts that are not appropriate to that purpose.isual representation of the tables and the rows of the tables.
