Section: 3.1.1.1

Original Text
-------------
 A parameter value that matches the token production can be
   transmitted either as a token or within a quoted-string.  The quoted
   and unquoted values are equivalent.  For example, the following
   examples are all equivalent, but the first is preferred for
   consistency:

     text/html;charset=utf-8
     text/html;charset=UTF-8
     Text/HTML;Charset="utf-8"
     text/html; charset="utf-8"


Corrected Text
--------------
 A parameter value that matches the token production can be
   transmitted either as a token or within a quoted-string.  The quoted
   and unquoted values are equivalent.  For example, the following
   examples are all equivalent, but the first is preferred for
   consistency:

     text/html;charset=utf-8
     text/html;charset=UTF-8


Notes
-----
Section 3.1.1.2 defines charset value to be a token. I consider this to be a bad example which might cause confusion. Why should I quote the value if it is defined as token?! You make want to use some other example.
 --VERIFIER NOTES-- 
   What's relevant is the ABNF for *parameter*, and that allows both token and quoted-string.  So the example is correct.
