36  * <p>This interface defines methods for accessing RDF Bag resources.
37  * These methods operate on the RDF statements contained in a model. The
38  * Bag implementation may cache state from the underlying model, so
39  * objects should not be added to or removed a the Bag by directly
40  * manipulating its properties, whilst the Bag is being
41  * accessed through this interface.</p

44  * iterator returned through this interface, all the other members with
45  * higher ordinals are renumbered using an implementation dependendent
46  * algorithm.</p>
