This OID is for International Standards and ISO Member Bodies.
Operation of this OID is in accordance with Rec. ITU-T X.660 | ISO/IEC 9834-1 "Procedures for the operation of object identifier registration authorities: General procedures and top arcs of the international object identifier tree".
All decisions related to child OIDs, other than the assignment of additional secondary identifiers to top-level OID 1 (see Rec. ITU-T X.660 (2004) | ISO/IEC 9834-1:2004, clause A.5), will be recorded as amendments to Rec. ITU-T X.660 | ISO/IEC 9834-1 (such changes to the common text will be regarded as editorial by ITU-T).
From Rec. ITU-T X.660 (2004) | ISO/IEC 9834-1:2004, "the top-level arcs are restricted to three arcs numbered 0 to 2; and the arcs beneath root arcs 0 and 1 are restricted to forty arcs numbered 0 to 39." This enables optimized encodings to be used in which the values of the top two arcs for all arcs under top-level arcs 0 and 1 encode in a single octet in an object identifier encoding (see the Rec. ITU-T X.690 series | ISO/IEC 8825 multi-part Standard).
