As an application, we discuss briefly how a complete description of the local gauge symmetries clarifies the properties of the supergravity-superbrane coupled system in the standard background superfield approximation for supergravity.12 pages, espcrc2 style, to appear in the Proc. of the Dubna-Wroclaw XVI-th Max Born SymposiumHigh Energy Physics - Theorytext
