/** 
 * A PrivateOwned annotation is used to specify a relationship is privately 
 * owned. A privately owned relationship means the target object is a dependent 
 * part of the source object and is not referenced by any other object and 
 * cannot exist on its own. Private ownership causes many operations to be 
 * cascaded across the relationship, including, deletion, insertion, refreshing, 
 * locking (when cascaded). It also ensures that private objects removed from 
 * collections are deleted and object added are inserted.
 * 
 * A PrivateOwned annotation can be used in conjunction with a OneToOne, 
 * OneToMany and VariableOneToOne annotation. Private ownership is implied 
 * with the BasicCollection and BasicMap annotation.
