Will review.

One thing I already noticed is that the spec does the same mistake most 
other header field definitions make; it defines an extensible syntax but 
then special cases the header field it defines itself.

Parsing should be uniform.


- if you take value-less tokens, you need to state whether




are equivalent or not.

- if values can be tokens or quoted-strings, you should state that both 
notations are equivalent, and are allowed everywhere, so are




the same thing?
