If the ASPs identify themselves with a unique ASP Id, they are separate ASPs. If they do not use a unique ASP Id, there is an error for that. If they do not identify themselves at all (no ASP Id) the SGP is welcome to treat them as independent ASPs. --brian > > thanks! > Best regards, Dario > > > > > Brian F. G.
