<p class="MsoNormal"><span lang="FR"><o:p> </o:p></span></p>
<p class="MsoNormal">This is a document I was supposed to send a few months ago (action item #33).
<o:p></o:p></p>
<p class="MsoNormal">I send it as it is, in case some of you have time to read it and think about it.
<o:p></o:p></p>
<p class="MsoNormal">Frank and Fran have sent lots of ideas (and more than ideas), that I have only partially taken into account.
<o:p></o:p></p>
<p class="MsoNormal">So there is much more do do. <o:p></o:p></p>
<p class="MsoNormal">This document is just the beginning. <o:p></o:p></p>
