I updated the page!! Wrote about fifty lines! I *know* I saved because I was 
discussing this with a friend over IM, showing him the link to the page. My 
edit is not in the page's history either.

Have anyone restored from a backup or something? :-S

I will just have to write the page AGAIN. (Feeling no love for MediaWiki 
right now.)

See the wiki page in hald an hour.

Everyone calls it Vorbis comment (some insist on vorbiscomment).

Maybe separating the implementation specs and the field name specs would 
solve the naming issue? Leaving the Vorbis comment title, but referring to 
Xiph's ‘Media Description Field Name Set recommendation‘ instead. 
Separating the specs could also lead to adoption of the field name set by 
other metaformats such as ID3.
