[poe] Issue: Missing type of a Constraint's unit property marked as Model

nitmws has just labeled an issue for https://github.com/w3c/poe as "Model":

== Missing type of a Constraint's unit property ==
In the IM 2.5.1 Constraint Class its property unit is defined this way:

> A Constraint may have none or one unit property value for the unit value of the rightOperand/Reference.

But this definition misses the type of the property values. 
I suggest:
* strict variant (as in ODRL 2.1): IRI (to refer to a Concept representing the unit)
* lax variant: IRI or literal value.

AND: I feel the the definition above is not clear; what is a property "for the unit value of the rightOperand/Reference."?
I suggest:
A Constraint may have none or one unit property value (of type ....) **to set** the unit **used for the** value of the rightOperand/Reference.
