 * IdFactory defines methods to construct new ItemIds.
 * This factory is intended to build ItemIds from the parameters
 * passed to the various create methods and should not make an attempt to
 * apply additional logic such as e.g. roundtrips to the server or resolution of
 * Paths. Similarly the SPI implementation namely the
 * {@link RepositoryService} must be able to deal with the various formats of
 * an ItemId, since a caller may not (yet) be aware of the uniqueID
 * part of an ItemId.
