Technical Summary This specification defines registration procedures for the message header field names used by Internet mail, HTTP, newsgroup feeds and other Internet applications. Benefits of a central registry for message header field names include: o providing a single point of reference for standardized and widely- used header field names; o providing a central point of discovery for established header fields, and easy location of their defining documents; o discouraging multiple definitions of a header field name for different purposes; o helping those proposing new header fields discern established trends and conventions, and avoid names that might be confused with existing ones; o encouraging convergence of header field name usage across multiple applications and protocols. Working Group Summary This has been reviewed in the IETF on the firstname.lastname@example.org maiing list but is not the product of an IETF Working Group. Protocol Quality Ned Freed reviewed the document for the IESG. RFC Editor note Please add a new section 3, Registry usage requirements, that says: RFCs defining new header fields for Internet mail, HTTP, or MIME MUST include appropriate header registration templates(s) (as given in Section 3.2) for all headers defined in the document in their IANA considerations section. Use of the header registry MAY be mandated by other protocol specifications, however, in the absence of such a mandate use of the registry is not required. In section 3.2.1 "An header" should be "A header". The third paragraph of section 3.4 should be changed to read: Publication in an RFC or other form of Open Standard document (per RFC 2026 , section 7) is sufficient grounds for publication in the permanent registry. At the end of the IANA considerations section replace the text Initial header registrations are provided by the following companion documents: o For mail message headers: Registration of mail header fields  o For HTTP message headers: Registration of HTTP header fields  No initial entries are provided for the provisional registry. with No initial registry entries are provided. and delete  and  from the references section.
