This part of ISO/IEC 9834 specifies the contents of register entries recording information about OSI document types, and assigning an unambiguous name of ASN.1 type OBJECT IDENTIFIER to OSI document type definitions.This part of ISO/IEC 9834 specifies the procedures for the operation of an International Registration Authority for OSI document types.NOTES1 Additional document types may already be defined in International Standards.2 Any authority empowered under the rules of ISO/IEC 8824 to allocate object identifiers can maintain a register of document types, identifying each type with an object identifier from the set that they are empowered to allocate. The authority may adopt any procedures it wishes for maintaining its register, provided that each object identifier is allocated to at most one document type definition, is not allocated to any other information object, and is never re-used, as specified in ISO/IEC 8824.The OSI document type names to which this document refers are for use in fields of communication protocols which need to identify the corresponding (partially-defined or fully defined) semantics, syntax, and operations specified in the register entries.A name registered in accordance with this part of ISO/IEC 9834 serves as an identification of the OSI document types defined in the corresponding register entry. Identification of a particular OSI document type from the class of OSI document types defined in a particular register entry is provided by parameters associated with the register entry.The presence of a register entry in the International Register does not carry any implications of required support for the OSI document types it defines in any carrier-standard implementation.NOTE - Nonetheless, within a register entry, requirements may be expressed relating to implementations claiming to support the entry.
