narrowerThan leftOperands

We have discussed “odrl:narrowerThan” Actions (to form a hierarchy and for conflict detection) which we now have added support for.
(which will replace the current skos:broaderTransitive property in the ontology for Actions.)

We also have a hierarchy in the Constraint Left Operands:
  https://w3c.github.io/poe/vocab/#constraintLeftOperandCommon <https://w3c.github.io/poe/vocab/#constraintLeftOperandCommon>

Such as:
  :absoluteSpatialPosition skos:broaderTransitive :absolutePosition;

We have 3 options now:
1 - re-use odrl:narrowerThan
2 - define a a new property
3 - keep using skos

We will not be evaluating Left Operands for conflict detection, so the relationship we are expressing is less critical (and more “semantic”).

I recommend we keep using skos for Left Operand relationships.
