Re: [poe] Review definitions of LeftOperands in the Common Vocab

Ok, as Editor of the Vocab I guess I should suggest required changes.
(Typographical note: inserted/changed language in **bold**)

I went over [4.5 Constraint Left Operands](http://w3c.github.io/poe/vocab/#constraintLeftOperandCommon) of the Vocab Editor's draft of 18 November, the number below follows the Vocab document.

1. Absolute Asset Position: sounds ok, refers to the Asset
2. Absolute Spatial Asset Position: sounds ok, refers to the Asset
3. Absolute Temporal Asset Position: sounds ok, refers to the Asset
4. Absolute Asset Size: sounds ok, refers to the Asset
5. Count: refers to nothing; I suggest: "Numeric count **of executions of the action of the Rule**"
6. Datetime: refers to nothing, I suggest: "The date (and optional time and timezone) **of exercising the action of the Rule**. ..."
7. Delay period: refers to nothing, I suggest: "A time delay period **prior to exercising the action of the Rule**. The point in time triggering this period MAY be defined by another temporal Constraint **combined by a Logical** Constraint (utilising the odrl:andSequence **operand**). ..."
8. Delivery Channel: not completely clear, a refined definition is "The delivery channel used **for exercising the action of the Rule**."
9. Elapsed Time: refers to nothing, I suggest: "A continuous elapsed time period **which may be used for exercising of the action of the Rule**." (Hm, what exactly is the difference between Elapsed Time and Metered Time? I assume: Elapsed Time is a single continuous period opening a time slot which may be used for exercising the action while Metered Time may be a collection of many different measured periods used for exercising the action.)
10. Event: refers to nothing, I suggest "An identified event **setting a context for exercising the action of the Rule**."
11. File Format: refers only indirectly, I suggest "A transformed file format **of the Asset**."
12. Industry Context: refers to nothing, I suggest "A defined industry sector **setting a context for exercising the action of the Rule**." 
13. Natural Language: refers to nothing, I suggest: "A natural language **used by the Asset**."
14. Media Context: refers to nothing, I suggest: "Category of a media asset **setting** a context **for exercising the action of the Rule**." 
15. Metered Time: refers to nothing, I suggest "An accumulated amount of **one to many metered** time period**s which were used for exercising the action of the Rule**." (See my comment on Elapsed Time.)
16. Pay Amount: this is a constraint to be used for refinements, I hand this over to #282 
17. Asset Percentage: refers to Asset only by the label, I suggest "A percentage amount **of the Asset relevant for exercising the action of the Rule.**"
18. Product Context: refers to nothing, I suggest: "**Category of** product or service **setting a context for exercising the action of the Rule**.
19. Purpose: refers to nothing, I suggest "**The** purpose **for exercising the action of the Rule**."
20. Recipient: slight modification "The party receiving the result/outcome **of exercising the action of the Rule**."
21. Relative Asset Position: sounds ok, refers to the Asset
22. Relative Spatial Asset Position: sounds ok, refers to the Asset
23. Relative Temporal Asset Position: sounds ok, refers to the Asset
24. Relative Asset Size: sounds ok, refers to the Asset
25. Rendition Resolution: sounds ok, refers to the Asset
26. Geospatial Named Area: unclear what it refers to, I suggest: "A named and identified geospatial area with defined borders **which is used for exercising the action of the Rule**. ..."
27. Geospatial Coordinates: this is a narrower term of 26. , I suggest to align it: "A set of coordinates setting the borders of a geospatial area **which is used for exercising the action of the Rule**. ..."
28. System Device: refers to nothing, I suggest: "An identified computing system **which is used for exercising the action of the Rule**."
29. Recurring Time Interval: refers to nothing, I suggest. "A recurring period of time **before the next execution of the action of the Rule**. ..."
30. Unit Of Count: refers to nothing and is semantically linked to Count, I suggest: "The unit of measure used for counting **the executions of the action of the Rule**.
31. Version: the definition refers to the Asset, but in a way which cannot be used for a constraint. I suggest "**The version of the Asset**".
32. Virtual IT Communication Location: refers to nothing, I suggest: "An identified location of the IT communication space **which is relevant for exercising the action of the Rule**.

... and I continue with a review of 4.6 Constraint Right Operands
1. Policy Usage Time and definition: "Indicates the time when the policy rule is exercised."
Sorry, but that is a mix of many things, the key issue is: definition and note talks about exercising a Rule, the label and the identifier talks about the Policy - that does not fit! As a Policy cannot be exercised I suggest:
  Re-identify the RightOperand by http://www.w3.org/ns/odrl/2/ruleExercise
  Label: Rule Action Exercise Time
  Definition: "Indicates the (date and) time when the action of the Rule is exercised."
  Note: sorry I don't understand it. How can a Constraint require that the action of a Rule is exercised before the Rule is exercised?? What does it mean "a Rule is exercised"?
?? What is the POE use case requiring to add this RightOperand?
