2. registers top-level arcs of the international OID tree;
   
3. specifies procedures which are generally applicable to registration at any level of the international OID tree;
   
4. provides guidelines for the establishment and operation of International Registration Authorities for use, when needed, by other ITU-T Recommendations and/or International Standards;
   
5. provides guidelines for additional ITU-T Recommendations and/or International Standards which choose to reference the procedures in ISO/IEC 9834-1:2012;
