Vorbis_I_spec.html needs updating
http://xiph.org/ogg/vorbis/doc/Vorbis_I_spec.html is outdated. On line 2166, it
mentions the old MIME type:
The correct MIME type of any Ogg file is <tt class="literal">application/x-
ogg</tt>.
CVS vorbis/doc/xml/a1-encapsulation_ogg.xml and
http://xiph.org/ogg/vorbis/doc/vorbis-ogg.html are up-to-date.
