At the moment, multiple instances of a template questionnaire by the same owner can't be differentiated by their activity ID. When issue #112 is resolved, this will apply to all copies of a template.
To differentiate between multiple instances, another context activity should by added to xAPI statements, under the other category. The activity should have an activity ID unique to the specific instance of the questionnaire.
