I'm confused by your answer.

http://www.openannotation.org/spec/core/#Motivation says that only
subclasses of oa:Annotation are motivations.  Doesn't this require
that if Jacco's "roles" are to be considered motivations, then they
must be modelled as subclasses, such as the AssociatedPersonClass you
say he doesn't need?
