13.2. Post the parameter definition The parameter description must be posted to the new parameter discussion list, ietf-mime-direct@imc.org13.3. Allow a comment period Discussion on the new parameter must be allowed to take place on the list for a minimum of two weeks. Consensus must be reached on the parameter before proceeding to step 4.13.4. Submit the parameter for approval Once the two-week comment period has elapsed, and the proposer is convinced consensus has been reached on the parameter, the registration application should be submitted to the Profile Reviewer for approval. The Profile Reviewer is appointed by the Application Area Directors and can either accept or reject the parameter registration. An accepted registration is passed on by the Profile Reviewer to the IANA for inclusion in the official IANA parameter registry. The registration can be rejected for any of the following reasons. 1) Insufficient comment period; 2) Consensus not reached; 3) Technical deficiencies raised on the list or elsewhere have not been addressed. The Profile Reviewer's decision to reject a profile can be appealed by the proposer to the IESG, or the objections raised can beHowes, et. al.

Parameter Change Control Existing parameters can be changed using the same process by which they were registered. Define the change Post the change Allow a comment period Submit the parameter for approval Note that the original author or any other interested party can propose a change to an existing parameter, but that such changes should only be proposed when there are serious omissions or errors in the published specification. The Profile Reviewer can object to a change if it is not backwards compatible, but is not required to do so. Parameter definitions can never be deleted from the IANA registry, but parameters which are nolonger believed to be useful can be declared OBSOLETE by a change to their "intended use" field.15. Registration of new value types This section defines procedures by which new value types are registered with the IANA and made available to the Internet community. Note that non-IANA value types can be used by bilateral agreement, provided the associated value types names follow the "X-" convention defined above. The procedures defined here are designed to allow public comment and review of new value types, while posing only a small impediment to the definition of new value types. Registration of a new value types is accomplished by the following steps.15.1. Define the value type A value type is defined by completing the following template. To: ietf-mime-direct@imc.org Subject: Registration of text/directory MIME value type XXXHowes, et. al. Standards Track [Page 28]RFC 2425 MIME Content-Type for Directory Information September 1998 value type name: value type purpose: value type format: value type special notes (optional): Intended usage: (one of COMMON, LIMITED USE or OBSOLETE) The explanation of what goes in each field in the template follows. value type name: The name of the value type as it will appear in the text/directory MIME Content-Type. value type purpose: The purpose of the value type. Give a short but clear description. value type format: The definition of the format for the value, usually using ABNF grammar. value type special notes: Any special notes about the value type, how it is to be used, etc.15.2. Post the value type definition The value type description must be posted to the new value type discussion list, ietf-mime-direct@imc.org15.3. Allow a comment period Discussion on the new value type must be allowed to take place on the list for a minimum of two weeks. Consensus must be reached before proceeding to step 4.15.4. Submit the value type for approval Once the two-week comment period has elapsed, and the proposer is convinced consensus has been reached on the value type, the registration application should be submitted to the Profile Reviewer for approval. The Profile Reviewer is appointed by the Application Area Directors and can either accept or reject the value type registration. An accepted registration should be passed on by the Profile Reviewer to the IANA for inclusion in the official IANA value type registry. The registration can be rejected for any of the following reasons. 1) Insufficient comment period; 2) Consensus not reached; 3) Technical deficiencies raised on the list or elsewhere have not been addressed. The Profile Reviewer's decision to reject aHowes, et. al. Standards Track [Page 29]RFC 2425 MIME Content-Type for Directory Information September 1998 profile can be appealed by the proposer to the IESG, or the objections raised can be addressed by the proposer and the value type registration resubmitted.16. Security Considerations Internet mail is subject to many well known security attacks, including monitoring, replay, and forgery. Care should be taken by any directory service in allowing information to leave the scope of the service itself, where any access controls can no longer be guaranteed. Applications should also take care to display directory data in a "safe" environment (e.g., PostScript-valued types).17. Acknowledgements The registration procedures defined here were shamelessly lifted from the MIME registration RFC. The many valuable comments contributed by members of the IETF ASID working group are gratefully acknowledged, as are the contributions of the Versit Consortium. Chris Newman was especially helpful in navigating the intricacies of ABNF lore.18. References [RFC-1777] Yeong, W., Howes, T., and S.
