243 * objects (styles) needing certain id. Object::build checks
244 * final id against it, and invokes necesary methods
245 *
246 * 2. Removing referenced object is simply prohibited -
247 * needs analyse, how we can deal with situations, where
248 * we simply want to ungroup etc. - probably we need
