Title: Event Sub-Process

Describe the issue:

While trying to highlight the capabilities of BPMS in an RFP response it was found that Section A.11.4.4. Event Sub-Process of the BPMS User Guide only states "Editor initialized empty topic content".

Suggestions for improvement:

Write at least some basic content for the section, and better - document when and why customers would use this "event sub-process" construct.
