RFC 3779, "X.509 Extensions for IP Addresses and AS Identifiers", June 2004Source of RFC: pkix (sec)

Section 188.8.131.52 says:
The ASIdentifiers type is a SEQUENCE containing one or more forms of autonomous system identifiers -- AS numbers (in the asnum element) or routing domain identifiers (in the rdi element). When the ASIdentifiers type contains multiple forms of identifiers, the asnum entry MUST precede the rdi entry. AS numbers are used by BGP, and routing domain identifiers are specified in the IDRP [RFC1142].
It should say:
IDRP was never defined in an RFC, only by ISO 10747.
