<p class='phone'><cite>erik:</cite> we can do it but not before
april</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; Silvia: I'm not
sure we need a responsible person, no stress on someone in
particular</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; ... it could be a
collective effort</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; Michael: I think
you're right, but getting a person setting up the policy for
external reviews is important</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; ... for that, it is
good to have a face</p>
<p class='phone'><cite>silvia:</cite> could be part of the
natural sequence of (1) defining use case, (2) defining
solution, (3) defining error and test cases</p>
<p class='phone'><cite>raphael:</cite> during f2f we could
