    <p class='phone'>RE: ACTION-134: Erik to mark up the spec with
    normative and informative classes</p>

    <p class='phone'><cite>raphael:</cite> thinks it's too early
    for such markup<br />
    ... should be last thing we do<br />
    ... still subject to lots of discussions<br />
    ... could start marking up on the parts that are major</p>

    <p class='phone'><cite>silvia:</cite> <a href=

    ... has a list of things that could be marked up already<br />

    <p class='phone'><cite>raphael:</cite> would rather want to get
    implementations</p>

    <p class='phone'><cite>mhausenblas:</cite> agree, statements
    are too early<br />
    ... could change still</p>

    <p class='phone'><cite>raphael:</cite> support the path that
    silvia mentions</p>

    <p class='irc'>&lt;<cite>mhausenblas</cite>&gt; Michael: we
    should flag stable vs. unstable sections rather than normative
    vs. informative</p>

    <p class='phone'><cite>raphael:</cite> just marking some

    <p class='phone'>michael hasn't had the time to spend on test

    <p class='phone'><cite>raphael:</cite> need another volunteer

    <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

    solution, (3) defining error and test cases</p>

    <p class='phone'><cite>raphael:</cite> during f2f we could

    above :)<br />
