51 | <h2 class="break">History</h2>
|
---|
52 | <ul>
|
---|
53 | <li>Extensions for non-ASCII characters in header field values using "parameter" syntax</li>
|
---|
54 | <li>RFC 5987 (2010) profiled the old MIME-related spec for use in HTTP</li>
|
---|
55 | <li>At that point already used for Content-Disposition by some user agents</li>
|
---|
56 | <li>During/after work on RFC 5987 picked up by the other user agents as well</li>
|
---|
57 | <li>...now interoperable (with a small twist)</li>
|
---|
58 | </ul>
|
---|
59 | <h2 class="break">Changes in RFC5987bis</h2>
|
---|
60 | <ul>
|
---|
61 | <li>Reduces set of supported charsets to just UTF-8 (reflecting Chrome and IE)</li>
|
---|
62 | <li>Now based on RFC 723*</li>
|
---|
63 | <li>Does not attempt to redefine "parameter" ABNF anymore (because there really is no common one in the HTTP specs right now)</li>
|
---|
64 | </ul>
|
---|
65 | <h2 class="break">Status</h2>
|
---|
66 | <ul>
|
---|
67 | <li>Most (all?) planned changes done, some cleanup might be required</li>
|
---|
68 | <li>Experimentally uses non-ASCII characters in examples (coordinated with both RSE and IESG)</li>
|
---|
69 | <li>Not clear yet whether we can continue that experiment if we finish before the RFC Format change activity is finished.</li>
|
---|
70 | <li>WGLC after next draft?</li>
