And the specification of "Accept-Language" is in rfc 3282 section 3
urn:ietf:rfc:3282 
http://tools.ietf.org/html/rfc3282#section-3 

There is a specification for http protocol only in 
rfc 2616 section 14.4
urn:ietf:rfc:2616
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.4
http://tools.ietf.org/html/rfc2616#section-14.4


The RFC 2616 is currently updated by a working group of IETF and W3C 
http://www.ietf.org/html.charters/httpbis-charter.html
