<div>
<p class="MsoNormal">Assuming no text has been added / crafted apart from the section 2 and section 11, I think I am done with it. <o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Two versions: One is more radical than the other: the file name indicates it. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">The radical one merges implicit and hybrid into Multiple Response Types. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">In fact, there is no pure "implicit" authentication. It is always Hybrid. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">So, this probably is more logical. I also got rid of the word "Code Flow". <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">It is an undefined word now that OAuth got rid of the term. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I replaced it with Code Grant. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I also removed bunch of redundant text. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">There are a few technical changes. Otherwise, though it may seem to be a lot of change, they are all editorial. Technical changes are marked in the comment with (te). <o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">1. The fragment handling. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Section 2.2.2.7 says that fragment has to be sent to the Web Server. This is not true. The javascript client may consume it by itself. This was a new text added in the new Core. I propose to remove it entirely. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">2. Relationship of Access Tokens<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The proposed text says they should be the same. I contend that they actually should be different. This, again, is a new text introduced in the new core. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">It is now almost 3:00am. I am going to the bed now. <o:p></o:p></p>
