<p class="MsoNormal">Been meaning to get to this… I have to say, it’s a big lump of text to take in. Two general questions: Did you still want comments posted on the review (D70523) or in some other fashion? And, would it be possible to more clearly identify
the new/changed bits of the sections that you are quoting from the spec? When I see a bunch of familiar text I’m inclined to skim over it, which means I’m likely to miss something that just has that subtle “New” on it. Maybe you could put a Note at those
points just to be a more obvious call-out.<o:p></o:p></p>
