*
* Given a set of ontologies, this composite change will convert all property assertion
* axioms whose subject is a 'punned' individual (i.e. an individual that shares a name
* with a class), removes these axioms and replaces them with annotations on the class
* that shares the same name as the individual. For example for a class A and an individual
* A, the data property assertion hasX(A, "Val") would be converted to an entity annotation on
* the class A with an annotation URI of "hasX" and a value of "Val".
*
* This composite change supports refactoring an ontology where punning was used to simulate
* annotations on a class rather than using actual annotations on a class.
