For the area of joint (ITU-T and ISO/IEC) registration within a
country
Information:
According to ITU-T X.660 (2004) | ISO/IEC 9834-1:2004, sub-clause A.4.5, "the values assigned to country-name arcs under this object-identifier are the integer values of the numeric-3 codes of ISO 3166 (without leading zeros). The node identified by a country-name arc may be used to assign object identifiers within a country. The administration of this node is not prescribed by Rec. ITU-T X.660 | ISO/IEC 9834-1, but is is recommended that a single national Registration Authority be determined by the joint decision of the country's ITU-T Administration and ISO/IEC National Body. The assignment of registration responsibilities within a country is a national decision."
This national decision doesn't need to be ratified by a formal joint Resolution of ITU-T SG17 and ISO/IEC JTC1/SC6 which are the subgroups responsible of Rec. ITU-T X.660 | ISO/IEC 9834-1. However, once an RA has been designated for a country OID, it is recommended that a letter be sent to inform both ITU-T SG17 and ISO/IEC JTC1/SC6, so that they can update the register of the superior OID, namely {joint-iso-itu-t(2) country(16)} (see example of such a letter).
