  ITU-T A.5 justification information for referenced document IETF RFC 2049 (1996) in draft X.1277
1. Clear description of the referenced document:
Name: IETF RFC 2049 (1996)
Title: Multipurpose Internet Mail Extensions (MIME) Part Five: Conformance Criteria and Examples (RFC 2049)
2. Status of approval:
November 1996 as Standards Track
3. Justification for the specific reference:
The referenced document constitutes provisions of this Recommendation
4. Current information, if any, about IPR issues:
The IETF Trust's Legal Provisions Relating to IETF Documents(http://trustee.ietf.org/license-info)
5. Other useful information describing the "Quality" of the document:
This memo provides information for the Internet community. It does not specify an Internet standard.
6. The degree of stability or maturity of the document:
This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements.
7. Relationship with other existing or emerging documents:
These documents are based on earlier work documented in RFC 934, STD 11, and RFC 1049, but extends and revises them. Because RFC 822 said so little about message bodies, these documents are largely orthogonal to (rather than a revision of) RFC 822. The initial document in this set, RFC 2045, specifies the various headers used to describe the structure of MIME messages. The second document defines the general structure of the MIME media typing system and defines an initial set of media types. The third document, RFC 2047, describes extensions to RFC 822 to allow non-US-ASCII text data in Internet mail header fields. The fourth document, RFC 2048, specifies various IANA registration procedures for MIME- related facilities. This fifth and final document describes MIME conformance criteria as well as providing some illustrative examples of MIME message formats, acknowledgements, and the bibliography. These documents are revisions of RFCs 1521, 1522, and 1590, which themselves were revisions of RFCs 1341 and 1342. Appendix B of this document describes differences and changes from previous versions.

9. Qualification of ISOC/IETF:
9.1-9.6     Decisions of ITU Council to admit ISOC to participate in the work of the Sector (June 1995 and June 1996).
9.7     The Internet Engineering Steering Group (IESG) is responsible for ongoing maintenance of the RFCs when the need arises. Comments on RFCs and corresponding changes are accommodated through the existing standardization process.
9.8     Each revision of a given RFC has a different RFC number, so no confusion is possible. All RFCs always remain available on-line. An index of RFCs and their status may be found in the IETF archives at http://www.rfc-editor.org/rfc.html.
10. Other (for any supplementary information):
None.
