The IETF will create a mailing list, email@example.com, which can be used for public discussion of iCalendar elements proposals prior to registration. Use of the mailing list is strongly encouraged. The IESG will appoint a designated expert who will monitor the firstname.lastname@example.org mailing list and review registrations.
Registration of new iCalendar elements MUST be reviewed by the designated expert and published in an RFC. A Standards Track RFC is REQUIRED for the registration of new value data types that modify existing properties, as well as for the registration of participation status values to be used in "VEVENT" calendar components. A Standards Track RFC is also REQUIRED for registration of iCalendar elements that modify iCalendar elements previously documented in a Standards Track RFC.
The registration procedure begins when a completed registration template, defined in the sections below, is sent to email@example.com and firstname.lastname@example.org. The designated expert is expected to tell IANA and the submitter of the registration within two weeks whether the registration is approved, approved with minor changes, or rejected with cause. When a registration is rejected with cause, it can be re-submitted if the concerns listed in the cause are addressed. Decisions made by the designated expert can be appealed to the IESG Applications Area Director, then to the IESG. They follow the normal appeals procedure for IESG decisions.
