This Recommendation / International Standard is intended to provide the ODP Reference Model (see ITU-T Rec. X.902 / ISO/IEC 10746-2 and ITU-T Rec. X.903 / ISO/IEC 10746-3) with a language and environment neutral notation to describe computational operation interface signatures. Use of this notation does not imply use of specific supporting mechanisms and protocols.
