BPMN21 — Table 7.2 Description of Multiple Instances

In the Table 7.2 description of Multiple Instances, it says in the second sentence that "A set of three horizontal lines will be displayed at the bottom-center of the activity for sequential Multi-instances." In the third sentence, it again says that the set of three vertical lines is also for sequential multi-instances. A revision needs to be made to correctly state what the three horizontal lines and three vertical lines stand for.
