Versions should be handled using the regular expression syntax of the archetype ID, as is done in ADL to represent slot constraints and action_arcehtype_id in ACTIVITY.
E.g. [openEHR-EHR-COMPOSITION.encounter.v1*] BTW, using the OR operator you could have had ... CONTAINS COMPOSITION [openEHR-EHR-COMPOSITION.encounter.v1] OR COMPOSITION [openEHR-EHR-COMPOSITION.encounter.v2] ...
