PPMN — No Graphical Notation for Properties

PPMN doesn't have a way to graphically show relationships between elements that are otherwise captured as attributes. An example is the location of an Entity or a Party. The metamodel supports capturing the fact that an Entity is at a location and while locations do have a graphical representation, there isn't any given graphical notation for showing that the Entity is at that location. This significantly degrades the ability to graphically show where things are in relation to one-another.
