The implied ordering constraints appear in subfigure (g) and (h)
http://dvcs.w3.org/hg/prov/raw-file/default/model/releases/WD-prov-dm-20120309/prov-dm-constraints.html#constraint-summary

and are expressed:
http://dvcs.w3.org/hg/prov/raw-file/default/model/releases/WD-prov-dm-20120309/prov-dm-constraints.html#wasStartedBy-ordering
http://dvcs.w3.org/hg/prov/raw-file/default/model/releases/WD-prov-dm-20120309/prov-dm-constraints.html#wasInformedBy-ordering

Note that wasStartedBy has become wasStartedByActivity since yesterday, 
but the change has not been implemented yet.
