    <p class='irc'>&lt;<cite>mhausenblas</cite>&gt; Michael: really
    two issues here</p><a name="action02" id="action02"></a>

    <p class='irc'>&lt;<cite>scribe</cite>&gt;
    <strong>ACTION:</strong> Yves to find out more about fragment
    identifier registration [recorded in <a href=
    "http://www.w3.org/2009/07/15-mediafrag-minutes.html#action02">http://www.w3.org/2009/07/15-mediafrag-minutes.html#action02</a>]</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; Created ACTION-89
    - Find out more about fragment identifier registration [on Yves
    Lafon - due 2009-07-22].</p>

    <p class='irc'>&lt;<cite>mhausenblas</cite>&gt; Michael: one is
    re the SHOULD re frags in sec 4.11 of RFC4288</p>

    <p class='phone'><cite>erik:</cite> status on a-62?</p>

    <p class='phone'><cite>Yves:</cite> sent a mail to TAG, but no
    feedback yet</p>

    <p class='irc'>&lt;<cite>mhausenblas</cite>&gt; Michael: other
    is re registered image/*, video/* and audio/* - to me the
    answer here is: no, MPEG21 only has registered application/mp21
    and hence we there is no clash</p>

    <p class='phone'><cite>mhausenblas:</cite> A-82 is still
    ongoing<br />
    ... this depends on reviewing and discussing the test cases</p>

    <p class='phone'><cite>erik:</cite> resolutions for i-4 and
    i-10?<br />
    ... no resolution yet on i-4, to be discussed further</p>

    <p class='irc'>&lt;<cite>mhausenblas</cite>&gt; Michael: re
    issue 10 the answer is easy</p>

    <p class='irc'>&lt;<cite>Gui</cite>&gt; We may need an action

    libraries in Java</p>

    <p class='irc'>&lt;<cite>Gui</cite>&gt; Jack ( I think ) has
    looked at libraries in Python</p>

    <p class='phone'><cite>Yves:</cite> looking for media slicing
    tools is part of the work, but do not depend on the
    syntax<br />
    ... so we can start working on this kind of things<br />
