Re: [poe] Subject of the Constraint

I copy and paste from my proposed refined left operand definitions, 
any subject beyond the Action is in **bold**:
- absoluteTemporalPositionAsset: The absolute temporal positions in a 
media stream the **Asset** has to fit in after the Action.
- fileFormatBefore:  The file format of the **Asset** before the 
Action is exercised.
- version: The range of versions of the **Asset** which can or cannot 
be used for exercising the Action.

In fact in these examples only the Asset is the alternative subject - 
and included into the free-text definition of the constraint.

Regarding a party as subject: I recall discussions where it was said 
that assignees could be constrained by a definition of this party, 
e.g. we have in a RightsML example "all customers of the 
assigner-company XYZ". 

A special facet of that are recipients: They are neither Assigner nor 
Assignee. But for that we have already a constraint: "The party 
receiving the result of an exercised Action." If one wants to 
constrain these people to students then the right operand value has to
 define a corresponding entity.
