 * <p/>
 * Would love for this to go away, but that would require that Hibernate's
 * internal {@link org.hibernate.engine.internal.JoinSequence join handling} be able to either:<ul>
 * <li>render the same AST structures
 * <li>render structures capable of being converted to these AST structures
 * </ul>

 * In the interim, this allows us to at least treat these "hidden" parameters properly which is
