    <p class='irc'>&lt;<cite>Gui</cite>&gt; +regrets Gui</p>

    <p class='phone'>Hi Guillaume, you cannot make the telecon?</p>

    <p class='phone'>Yves, try to dial another number?</p>

    <p class='irc'>&lt;<cite>scribe</cite>&gt; scribenick:
    raphael</p>

    <p class='phone'>Topic 1. ADMIN</p>

    <p class='phone'>Propose to accept the minutes of last
    telecon?</p>

    <p class='phone'><cite>All:</cite> accept without changes</p>

    <p class='phone'><strong class='resolution'>RESOLUTION: minutes
    accepted</strong></p>

    <p class='phone'>Topic 2. F2F meeting</p>

    <p class='phone'><cite>Raphael:</cite> we need to discuss the
    agenda, build it together<br />
    ... what are your objectives?</p>

    <p class='phone'><cite>Jack:</cite> it would be good if we
    could discuss concrete implementations<br />
    ... mine could be ready, if we clarify the range unit
    syntax<br />
    ... then it is a 1/2 day coding</p>

    <p class='phone'><cite>Raphael:</cite> my expectation would be
    also to discuss test cases, and of course the main document</p>

    <p class='phone'><cite>Yves:</cite> we need to build a story
    around the 4-ways handshake<br />
    ... also talk about the link header</p>

    <p class='phone'>Topic 3. Main Document</p>

    <p class='phone'>3.1: Syntax</p>

    <p class='phone'>ACTION-46?</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; ACTION-46 -- Yves
    Lafon to check the formal validity of the grammar -- due
    2009-03-25 -- OPEN</p>

    "http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/46">http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/46</a></p>

    <p class='phone'>close ACTION-46</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; ACTION-46 Check
    the formal validity of the grammar closed</p>

    <p class='phone'><cite>Yves:</cite> I have built a small parser
    in java / cc that validates the grammar<br />
    ... no mistake in the grammar</p>

    <p class='phone'>3.2 Use Cases and requirements</p>

    <p class='phone'>Silvia and Guillaume will finish it by the end
    of this week</p>

    <p class='phone'>3.3 Technology Survey</p>

    <p class='phone'>Erik would like to know if he could take
    action to improve this section</p>

    <p class='phone'><cite>Raphael:</cite> what changes can we
    bring?<br />
    ... I think for example that the formal grammar of TimedText is
    unnecessary</p>

    <p class='phone'><cite>Jack:</cite> what about a companion
    document ?<br />
    ... I would suggest summarize the wiki page in the main
    document<br />
    ... and provide an informative reference to the complete wiki
    page<br />
    ... I would like to have this technology survey perhaps
    published as a Working Group note since I find it useful</p>

    <p class='phone'><cite>Davy:</cite> 5.1 should be in the ref
    section</p>

    <p class='phone'><cite>Raphael:</cite> yes, the examples come
    actually from 5.3</p><a name="action01" id="action01"></a>

    <p class='phone'><cite>Yves:</cite> I will definitively make

    <p class='phone'><cite>Jack:</cite> do you want to copy the
