          o This issue is a follow-on to issue ISSUE-447 (subactivity)
            <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.
