Nautilus uses audio/x-vorbis+ogg and video/x-theora+ogg internally, in<br>analogy with things like application/rss+xml. Do you know if the '+'<br>thing is a real proposal or just an experimental convention?</blockquote><div>
<br>From what I remember hearing (on the RSS Public mailing list -- <a href="http://tech.groups.yahoo.com/group/rss-public/">http://tech.groups.yahoo.com/group/rss-public/</a> )... the "+" thing was considered a hack. And it was intended to be a one-time hack... only for XML.
<br><br>(From other places I heard....) This new XML MIME types were basically a fix for the "text/xml" MIME type problem. "text/xml" was broken because "text/*" implies US ASCII encoding (because of the "text/" part) I believe... but XML defaults to UTF-8... and can be changed to other stuff from within the XML file. The real problem came when text-transcoders... which are common in parts of the Internet that are dominated by languages like Japanese, Chinese, etc... would do a text-transcode on XML assuming it was US ASCII... which would often totally mess it up and totally corrupt the XML file. (Which was really really bad.)
<br><br>So... based on that... which could of course be wrong (given that I can't find the actual message that was said in)... I don't believe they'd allow something like that to be registed again (outside of XML).<br> </div>

</a><br><br>(I know this is getting off topic, but....) Other idea could be to allow multiple content types for a "resource". So, for example, a SMIL file could have...<br><br>X-Content-Type<span style="font-weight: bold;">
