The new draft can be found at URL:
The title has been changed to " Mail, Netnews and HTTP header field Registration Procedure" so that also HTTP headers are included.
This registry can contain header fields starting with "X-", even though such header fields cannot be specified in IETF standards.
The header field name registry can contain header fields from the following sources: - Internet standards - RFCs which are not Internet standards - Non-Internet standards - Other commonly used headers fields - Headers implemented in new products - Sometimes used header fields whose use is discouraged.
The registry can contain header fields used in e-mail message headings, MIME content headings, HTTP headings and Usenet News article headings.
4.1 Registration Template To: email@example.com Subject: Registration of header field: XXX Header field name: Header field status (choices, see section 5.2 Header field Status below) Applicability: (One of COMMON, LIMITED USE or OBSOLETE) What is the header field used for: Who can set or modify the header field: Protocols which use this header field: (One or more of E-MAIL MESSAGE HEADING, E-MAIL CONTENT HEADING, HTTP HEADING, USENET NEWS HEADING) Application programs which use this header field: Encoding considerations: Security considerations: Interoperability considerations: Published specification: Person & email address to contact for further information: Author/Change controller: (Any other information that the author deems interesting may be added below this line.)
(1) In plain formatted ASCII text as shown in section 11.1. (2) In HTML format as shown in section 11.2. (3) As ASCII text with HT between fields and CRLF between lines as shown in section 11.3.
4.4 Changes to registered headers Minor changes to registered headers, which will not cause problems for those who have already implemented the header, can be done by the person or organisation who has change control for the header. This person or organisation can also add to the register advance notice about future changes under development. Changes made by an revised version of an IETF standard should be made at the same time as the publication of the revised standard. Other changes require the same approval procedure as for registration of new headers. 4.5 Registration of headers from Internet drafts Headers in Internet drafts can be registered on a temporary basis, so that the header registry can be used to find also such headers. If the IETF draft expires, such headers must either be removed from the registry, or changed to reflect their new status (as an IETF standard or as a non-standard documented separately from IETF).
The appendix has been modified to show examples of the three new publication formats. These examples can also be found at URL http://dsv.su.se/jpalme/ietf/iana-header-field-registry.html
