11、dization) 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 organizatio
12、n 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, IS
13、O 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
14、 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 pa

Amendment 1 to International Standard ISO/IEC 8824-2:2002 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 6, Telecommunications and information excha

18、 1 Support for EXTENDED-XER NOTE All new or changed text in this amendment is underlined in the clauses being replaced. When merging all such text into the base Recommendation, the underlining is to be removed. 1) Subclause 14.6.1 In subclause 14.6, replace the production “XMLOpenTypeFieldValue“ wit
19、h the following: XMLOpenTypeFieldVal := XMLTypedValue | xmlhstring 2) Subclause 14.9 Replace subclause 14.9 with the following three subclauses: 14.9 For a type field or a variable-type value or value set field defined by an “ObjectClassFieldType“, the “XMLOpenTypeFieldVal“ shall be used in any “XML
20、Value“. 14.9.1 When used in an ASN.1 module, the type identified by the “XMLTypedValue“ shall be any ASN.1 type (but see ITU-T Rec. X.680 | ISO/IEC 8824-1, 13.3) and the “XMLValue“ in the “XMLTypedValue“ shall be any value of that type. NOTE When the notation is used as specified in ITU-T Rec. X.693
21、 | ISO/IEC 8825-4, 8.5, the type of the “XMLTypedValue“ in an “XMLOpenTypeFieldVal“ is identified by the protocol (for example, by a component relation constraint), the “NonParameterizedTypeName“ in the “XMLTypedValue“ is derived from this, and the “XMLValue“ is a value of this type. 14.9.2 The “xml
22、hstring“ alternative of “XMLOpenTypeFieldVal“ shall not be used in an ASN.1 module. This alternative can be used only as specified in ITU-T Rec. X.693 | ISO/IEC 8825-4, 8.5, when the type is identified by the protocol and the “xmlhstring“ is the hexadecimal value for the encoding of that type, using
23、 some (unspecified) encoding rules. 3) Subclause 14.12 Replace subclause 14.12 with the following: 14.12 For an “XMLOpenTypeFieldVal“, if the “Type“ specified in the information object (after ignoring any tags) is a “typereference“ or an “ExternalTypeReference“, then the “NonParameterizedTypeName“ s
24、hall be that “typereference“ or “ExternalTypeReference“; otherwise, it shall be the “xmlasn1typename“ specified in ITU-T Rec. X.680 | ISO/IEC 8824-1, Table 4, corresponding to the built-in type specified in the information object, after application of the subclauses of ITU-T Rec. X.680 | ISO/IEC 882

X.681 (2002)/Amd.1 (10/2003) 4) Subclause 15.6 Replace subclause 15.6 with the following: 15.6 For a “TypeFromObject“ and a “ValueSetFromObjects“, the XML value notation for sequence-of and set-of (see ITU-T Rec. X.680 | ISO/IEC 8824-1, Table 5) and the “xmlasn1type
27、name“ (if required) shall be determined by the “Type“ specified in the information object(s), after application of the subclauses of ITU-T Rec. X.680 | ISO/IEC 8824-1, 25.11, if applicable. 5) Annex F In Annex F, replace the production “XMLOpenTypeFieldValue“ with the following: XMLOpenTypeFieldVal
