RFC 1838 RFC 822/X.400 Mapping by X.500 August 1995 2. Omitted Components In RFC 1327, it is possible to have omitted components in O/R Addresses on either side of the mapping. A mechanism to represent such omitted components is defined in Figure 2. The attribute at-or-address-component-type is set to the X.500 attribute type associated with the omitted component (e.g., at-prmd- name). This mechanism is for use only within the X.400 to RFC 822 subtree and for the at-associated-or-address attribute. ----------------------------------------------------------------------- rFC822ToX400Mapping OBJECT-CLASS ::= { SUBCLASS OF {domain-component} MAY CONTAIN { associatedORAddress| associatedX400Gateway} ID oc-rfc822-to-x400-mapping} x400ToRFC 822Mapping OBJECT-CLASS ::= { SUBCLASS OF {top} MAY CONTAIN { 10 associatedDomain} ID oc-x400-to-rfc822-mapping} associatedORAddress ATTRIBUTE ::= { SUBTYPE OF distinguishedName SINGLE VALUE ID at-associated-or-address} 20 associatedX400Gateway ATTRIBUTE ::= { SUBTYPE OF mhs-or-addresses MULTI VALUE ID at-associated-x400-gateway} associatedDomain ATTRIBUTE ::= { SUBTYPE OF name WITH SYNTAX caseIgnoreIA5String SINGLE VALUE ID at-associated-domain} 30 Figure 1: ObjectClasses for RFC 1327 mappings Kille Experimental
