BPMN21 — Page 283. The number of types of Event handlers

It says:
“There are three (3) types of Event handlers: those that start a Process, those that are part of the normal Sequence Flow, and those that are attached to Activities, either via boundary Events or via separate inline handlers in case of an Event Sub-Process.”

Actually, there are four Sub-Sections:
1) Handling Start Events (p.283)
2) Handling Events within normal Sequence Flow (Intermediate Events) (p. 284)
3) Handling Events attached to an Activity (Intermediate boundary Events and Event Sub-Processes) (p.285). With two sub-sub-.sections.
4) Handling End Events (p.288)

Then, it should say:
“There are four (4) types of Event handlers: those that start a Process, those that are part of the normal Sequence Flow, those that are attached to Activities, either via boundary Events or via separate inline handlers in case of an Event Sub-Process, and those that end a Process.”

“three (3) types” should be replaced by “four (4) types”
“and those that are attached to Activities” should be replaced by “those that are attached to Activities”
“Event Sub-Process.” should be replaced by “Event Sub-Process, and those that end a Process.”
