Issue 662: Explore the connection among I11 Situation, S23 Position Determination, and E3 Condition State

In the 57th CIDOC CRM & 50th FRBR/LRMoo SIG Meeting, upon discussing issue 550, the SIG resolved to start a new issue where to explore the connection among I11 Situation, S23 Position Determination, and E3 Condition State. 

Motivation: 
The difference btw E3 Condition State and I11 Situation is not particularly clear. And in that sense, it’s not 100% clear what the added value of the timespan of an I11 Situation offers. 
The SIG should explore and carefully define the relation between E3 Condition State and I11 Situation. 

• In principle, Jxxx1 held at least for seems to work well with E3 Condition state, which means that there could be implications for the hierarchical relations of I11 and E3.

Determine the constraints put on an instance of I4 Proposition Set (and/or I11 Situation) in the sense of defining the properties that can form part of the I4 instance. This should apply to subclasses of I4 (so if E3 is considered IsA I4, it would apply to it too). 
In determining the relation between I11 Situation and E3 Condition State, we must keep in mind that while it is the case that E3 IsA E2 Temporal Entity, it is not the case that I11 IsA E2 (I11 can be placed in the future).

• The relation of the modelling constructs around I11 Situation need to take into consideration S23 Position Determination and O31 has validity time-span as well. 

HW: MD, WS to work on that.
