Hi Thierry, All --

Thanks again for your efforts on getting us organized to move forward.

I'd like to comment on a couple of things, embedded...

We will of course have to adjust the start and finish somewhat, after we 
sort out our startup schedule.  But one initial thought:  I think we should 
close a bit earlier, if we anticipate a f2f Nov.19-21.  I think that 10-14 
days before would be better.  For example, if the f2f were Wed-Fri, then 
close something like Friday Nov.7, which is a week-and-a-half earlier.

Reason.  It gives us a chance to clarify and pre-negotiate any other WG's 
comments.  And maybe will help avoid a situation like last time, where we 
got comments just before the end of the Cologne F2F!

Looking at the charter, the motivation for SMIL & SVG are tied to 
animation.  We had declarative animation in the requirements as a 
"maybe".  But we flagged it as probably beyond the scope of 2.1, and indeed 
that is how we are progressing.

Question.  How does the postponement of declarative animation affect the 
SVG and SMIL dependencies?  (Should the pre-announce mention it?)  Note 
that there are some "hooks" that have been put into 2.1 that allow DOM 
script writers to more easily produce certain kinds of simple animation 

Comments anyone?
