BPMN 2.0 uses three different classes to represent groupings, but there is only one symbol: Group. Thus, a group is the graphical representation of a category value.

Categories and their category values are modeled in an auxiliary model of type Structuring model.

In ARIS the graphical element Group is an occurrence copy of a category value object and is depicted by a special symbol in the BPMN 2.0 models. The symbol name is Group.
