if the media type registration need to be in the same document as the payload specification.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Look in RFC 4855 (<a href="http://tools.ietf.org/html/rfc4855">http://tools.ietf.org/html/rfc4855</a>)
for published specification, there it says that registration and the payload
specification can be different documents.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

RFC that update the registration for example by adding parameters. <o:p></o:p></span></p>

<p><span style='font-family:"Calibri","sans-serif"'>I have the following doubt,

<p><span style='font-family:"Calibri","sans-serif"'>Is it mandatory that a
media type registration be included in the RFC that defines such media type?</span>

<p><span style='font-family:"Calibri","sans-serif"'>It seems to me, if I am not
mistaken, that there are several media types defined in RFCs which does not
contain an explicit media type registration….</span><o:p></o:p></p>
