PPMN — The statement in line 959, "Entities may represent some other thing of interest through EntityURI property," is ambiguous

The statement in line 959, "Entities may represent some other thing of interest through EntityURI property," is ambiguous. What kind of relationship is "represent"? Is it a reference, correlation, or some undefined relationship? Depending on the definition of this relationship, we may introduce some inconsistencies in the metamodel.
Furthermore, table 5 in line 984 defines "entityURI" as "A URI to the Entity". This is ambiguous and difficult to reconcile with line 959.

This Issue was not resolved in this Task Force and was automatically deferred to the next Task Force
