Issue 598: How to specify possible observable situations in the future

In the 53rd CIDOC CRM & 46th FRBRoo SIG meeting, following discussion of issue 583 at the 53rd SIG meeting, it was clarified that Observable Entities as subclass of E93 Presence can only be placed in historical time. A similar construct of defining the constraints of future possible Observable Entities needs to be discussed in a new issue. This will also need to take into account the CRMact model.
