BPMN21 — Event Sub-Process only in Sub-Processes?

Chapter 12.2.5 defines on page 178 (208 pdf)
'An Event Sub-Process is a specialized Sub-Process that is used within a Process (or Sub-Process)'

Chapter 13.4.4 defines on Page 452 (482 pdf)
'Event Sub-Processes allow to handle an Event within the context of a given Sub-Processes or Process.'

The second paragraph of Chapter 13.4.4 specify the cancel/parallel execution of the enclosing Sub-Process. If the Parent Process is not a Sub-Process but a Process, there is no definition.

Solution:
Replace in the second paragraph 'enclosing Sub-Process' with 'Parent Process' (2x).
