I need GNAT to accept it as such. In a more distant perspective I need a work-around of stream attributes. They are non-portable, so there must an option to replace them for DSA and/or provide a non-stream parameter marshaling when the transport is a higher-level protocol, e.g. CANopen, EtherCAT, ASN.1, AMQP etc. For these you must map Ada types into the types defined by the protocol. Without this DSA is pretty much pointless. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
