Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 2 to ISO/IEC 8824-1:2002 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 6, Telecommunications and information exchange between
systems in collaboration with ITU-T. The identical text is published as Amendment 2 to ITU-T Rec. X.680.

INTERNATIONAL STANDARD
ITU-T RECOMMENDATION
Information technology –
Abstract Syntax Notation One (ASN.1) –
Specification of basic notation
Amendment 2
Alignment with changes made to ITU-T Rec. X.660 | ISO/IEC 9834-1 for identifiers
in object identifier value notation
Conventions used in this amendment: Original, unchanged, text is in normal font. Deleted text is struck-through, thus:
deleted text. Inserted text is underlined, thus: inserted text.
1 Subclauses 31.7 and 31.9
In ITU-T Rec. X.680 | ISO/IEC 8824-1, replace 31.7 and 31.9 (Object Identifier) with:
31.7 The "NameForm" shall be used only for those object identifier components whose numeric value and
identifier are specified in ITU-T Rec. X.660 | ISO/IEC 9834-1, Annexes A to C (see also Annex D of this
Recommendation | International Standard), and shall be one of the identifiers specified in ITU-T Rec. X.660 | ISO/IEC
9834-1, Annexes A to C.
NOTE – Where the "NameForm" is allowed, the use of the "NameAndNumberForm" instead has been recommended in some
circumstances by ITU-T Rec. X.660 | ISO/IEC 9834-1, A.1.2.
31.7 bis Where ITU-T Rec. X.660 | ISO/IEC 9834-1 specifies synonymous identifiers, any synonyms may be used
under conditions established when the synonym was registered in accordance with ITU-T Rec. X.660 | ISO/IEC
9834-1with the same semantics. Where the same name is both an identifier specified in ITU-T Rec. X.660 | ISO/IEC
9834-1 and an ASN.1 value reference within the module containing the "NameForm", the name within the object
identifier value shall be treated as an ITU-T Rec. X.660 | ISO/IEC 9834-1 identifier.
31.9 The "identifier" in the "NameAndNumberForm" and "XMLNameAndNumberForm" shall be specified when
a numeric value is assigned to the object identifier component. There is flexibility in the "identifier"s that can be used in
the "NameAndNumberForm" and "XMLNameAndNumberForm" beneath the three top-level arcs. These identifiers are
not included in encodings, and may change over time. This is in recognition that the names of organizations can change.
Identifiers for arcs should normally be agreed between the Registration Authority responsible for the node above an arc,
and the Registration Authority to which responsibility for subsequent arcs has been assigned.
NOTE – The Registration Aauthorities allocating numeric values to object identifier componentsresponsible for arcs beneath the
three top-level arcs are identified in ITU-T Rec. X.660 | ISO/IEC 9834-1.
2 Subclauses D.1 to D.4
In ITU-T Rec. X.680 | ISO/IEC 8824-1, replace D.1 to D.4 with:
D.1 RootTop-level assignment of object identifier component
