That may be the case, byt my concern is trying to detect and recognize a 
vorbis file. I understand that an ogg file is just a 'container' format.

My concern is how to 'detect' what is inside this Ogg format and tell 
what kind of data is enclosed in it

Then how does an app (like a command-line app (e.g. 123)) able to say "I 
can only handle the vorbis codec". The "standard" way for it to be able 
to do that is through the mime-type of the file ("oh its audio/ogg - I 
can handle that" or "nope, I can't handle video/ogg"). 

The current way it is, we have to be able to support all possible 
permutations of possible Ogg formats, or we can't support it all.

I'm just trying to outline the problem that I have right now. I'm not 
necessarily advocating a change to Ogg, or criticizing the way it handles 
itself. I would just like a possible solution or workaround for my 
problem ;)
