http-equiv

Hi,

feedback on "Define how to register new http-equiv values. (credit: ma) 
(whatwg r2548)":

<http://www.whatwg.org/specs/web-apps/current-work/#other-pragma-directives>:

"...Such extensions must use a name that is identical to a 
previously-registered HTTP header defined in an RFC, and must have 
behavior identical to that described for the HTTP header...."

HTTP headers do not need to be defined in RFCs, there's a registry for 
it. See <http://tools.ietf.org/html/rfc4229>, 
<http://www.iana.org/assignments/message-headers/prov-headers.html>, and 
<http://www.iana.org/assignments/message-headers/perm-headers.html>.

BR, Julian
