[poe] Use of the label Left Operand in the ontology/vocabulary

nitmws has just created a new issue for https://github.com/w3c/poe:

== Use of the label Left Operand in the ontology/vocabulary ==
The ODRL Vocabulary & Expression Editor's Draft of 16 January 2017 
uses the label "Left Operand" two times:

- http://w3c.github.io/poe/vocab/#term-leftOperand (4.12.6) identifier
 =        http://www.w3.org/ns/odrl/2/leftOperand - used for the 
property of a left operand in Constraint class
- http://w3c.github.io/poe/vocab/#term-LeftOperand (4.12.7) identifier
 =        http://www.w3.org/ns/odrl/2/leftOperand - used as the class 
of things being a left operand.

At POE calls it was said the distinction between leftOperand and 
LeftOperand in the identifiers could be confusing, but having the same
 label for different things causes even more confusion.
