ITU-T Recommendation X.662 | ISO/IEC 9834-3 specifies the procedures for operating the International Registration Authority for assignment of values to object identifier arcs beneath the top-level arc with primary integer value 2, Unicode label Joint-ISO-ITU-T and secondary identifier joint-iso-itu-t. Assignment of the authority to allocate arcs beneath such arcs is either given to a specific area of work approved jointly by ISO/IEC and ITU-T (and is normally recorded in Recommendations | International Standards) or is given to an international organization.
