nTitle:   INFORMATION  TECHNOLOGY  –  OPEN  SYSTEMS  INTERCONNECTION  –  PROCEDURES FOR  THE  OPERATION  OF  OSI  REGISTRATION AUTHORITIES:  ITU-T REGISTRATION  OF INTERNATIONAL ORGANIZATIONS REGISTRATION
nThis is one of two Recommendations for registration of International Organizations.
nThis registers under the ITU-T arc to ITU-T Members.
nThe other (X.666) registers organisations under the joint ISO/ITU-T arc.
nFor totally historical reasons, this is quite different from X.666 text.  X.666 is probably the more important and better text.
