This is a XGraphicObjectResolver (future) replacement as it will not be needed anymore. All resolving from URL to URL will be replaced by loading, saving and serialization of XGraphic objects (when appropriate), which is covered by this interface and implementation by XmlGraphicHelper - the same that implements the XGraphicObjectResolver.
