            <http://www.w3.org/2011/prov/wiki/ResponsesToPublicComments#ISSUE-447_.28subactivity.29>
          o The working group has decided that it would not specify a
            "subactivity" relationship between activities.
          o Therefore this suggestion will not be adopted.

Like generation and usage, it might be advantageous to add support for "activity wasPartOf activity" so that one can model a startup process that takes time and may reference other entities or activities. This would allow users to consider starting an activity as a separate activity, which has a defined start and end time and which could be ended (perhaps prematurely) by some triggering event.
