 * HACK mechanism TODO REMOVE
 * 
 * The purpose of this handler is to create a element class from an existing one
 * in such a way that it is compiled to be used with the specified diagram.
 * 
 * This is hacky, but is at the moment needed for copying elements from one
 * diagram to another because the element classes sometimes need to be augmented
 * with diagram specified handlers.
