Hmm, no such possilbity, it's all or one... What's the usefulness?

If someone makes up a new header, and we decide we like it and add it to 
info table, using the old method, old demuxers not knowing the new info 
entry would crap out on the entire info packet because of the v/vb stuff. 
With the type stuff, it can be done in backwards compatible way, lacking 
the demuxer just understand the new header...

Also it's done in a way where we can force muxers to use rational and not 
float for some values or similar... Or force utf-8, etc.

I'm assuming you mean the totally incorrect way I did it, sorry, I was 
confused. :) Already sent a fixed patch.
