BPMN21 — Page 115. Confusion over subtypes of Collaboration 1.

It says
“When Participants are defined they are contained within a Collaboration, which includes the sub-types of Choreography, GlobalConversation, or GlobalChoreographyTask.”

This is not consistent with what is shown in Figure 9.1 (p.109): GlobalConversation and Choreography are sub-types of Collaboration; and GlobalChoreographyTask is sub-type of Choreography.

Maybe it should say
“When Participants are defined they are contained within a Collaboration, which includes the sub-types GlobalConversation, Choreography and GlobalChoreographyTask.”
