"agreed on 4 Dec 2003

    The 3 Dec 2003 Editor's Draft of the Architecture Document accurately represents the TAG's position on the authoritative nature of server messages. "
http://www.w3.org/2001/tag/issues.html#contentTypeOverride-24

"For me this questions depends on whether the document type is a human-readable hypertext document, when generic hypertext xml tools would benefit from knowing what is a link, and whether significance of the URI in question is a hypertext link or something different.

Maybe a compromise is to only allow the link to specify the content-type when the server is FTP (or something else with no content-type control) or the HTTP server returns text/plain or octet-steam, which seem to be used for "don't know" types."
 -- TimBL http://lists.w3.org/Archives/Public/www-tag/2002Jun/0116.html

On 21 May 2009, we agreed not to schedule discussion of this issue until Larry makes progress on ACTION-261.  We also agreed Noah would make preliminary inquiries with Mark Nottingham and Lisa Dessault per ACTION-257 to see whether there are dates between now and mid-July when they might join us on a teleconference.
