 * For some reason the Jcr-mapping framework has an interface and class which contain

 * {@link org.apache.portals.graffito.jcr.mapper.model.MappingDescriptor} but they 
 * are not related; actually they reside in different packages.
 * Thus if the mapping descriptors are created programatically or by other means
 * it's not possible to use them because a mapper is required.
 * 
 * This class bridges the two making possible to have mapper implementations different
 * then the digester.
