    - Book zakim for the 2 days meeting of the group on Mon 1st and

    <p class='phone'>ACTION-183?</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; ACTION-183 --
    Raphaël Troncy to send reminders to all relevant groups -- due
    2010-09-15 -- OPEN</p>

    <p class='phone'>I have not yet done this for IETF, TAG</p>

    <h3 id="item03">3. MEDIA FRAGMENT EXTENSION:</h3>

    <p class='phone'><cite>Erik:</cite> no more news from
    Michael/Conrad should we be concerned?</p>

    <p class='phone'><cite>Raphael:</cite> I don't think so ...
    there are no critical actions from them we depend on<br />
    ... if they can provide feedback, it's good<br />
    ... we must progress without waiting</p>

    <p class='phone'>Philippe's proposal: <a href=

    http://lists.w3.org/Archives/Public/public-media-fragment/2010Aug/0005.html</a></p>

    <p class='phone'><cite>Philippe:</cite> this is just one part
    of the problem<br />
    ... we could include this piece of ABNF in the doc</p>

    <p class='phone'>ACTIOn-173?</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; ACTION-173 -- Yves
    Lafon to produce the code that will check the grammar of both
    the URI syntax and the Headers syntax -- due 2010-06-22 --

    <p class='phone'>ISSUE-19?</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; ISSUE-19 --
    Parsing must be defined normatively in the MF spec itself --
    open</p>

    <p class='phone'><cite>Yves:</cite> action is still
    pending<br />
    ... what I would like to have is what goes in the javascript
    stack from the browsers when they meet a %encoded URL<br />
    ... %encoded and html-encoded URL (with ampersand)</p>

    <p class='phone'><cite>Erik:</cite> is this browser
    independent?</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; html entities:
    &amp;amp;</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; percent encoding:
    %64</p>

    <p class='phone'><cite>Philippe:</cite> this never reaches
    javascript, this is handled by the HTML parser<br />
    ... for percent encoding, yes, the js sees the un-decode
    string</p>

    <p class='phone'><cite>Yves:</cite> could you send to the
    mailing list the tests you have made so we can test on another
    browser than Opera</p>

    to the mailing list for understanding how browsers handle
    %-encodded and html-encoded URL [recorded in <a href=

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; Created ACTION-186
    - Send his list of test cases to the mailing list for
    understanding how browsers handle %-encodded and html-encoded
    URL [on Philip Jägenstedt - due 2010-09-29].</p>

    <p class='phone'><cite>Erik:</cite> what's happened if browsers
    manage this inconsistently?</p>

    <p class='phone'><cite>Raphael:</cite> the related problem
    deals with extensibility<br />
    ... of the URI syntax</p>

    <p class='phone'><cite>Philip:</cite> the whole thing is to
    have a break into name/value pairs<br />
    ... and then be relaxed if you don't understand all name/value
    pairs<br />
    ... I think we should have a syntax, that mandates what we
    should have as name/value<br />
    ... parsers fail for typos<br />
    ... but implementations should be more relaxed</p>

    <p class='phone'><cite>Yves:</cite> what bothers me that the
    ABNF tells both what the syntax is and how to parse it<br />
    ... the big issue is something that is not a media fragment can
    be recognized as a Media Fragment</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; "parsers fail for
    typos" isn't correct</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; a validator would,
    but not a parser in a browser</p>

    <p class='phone'><cite>Yves:</cite> we could put an algorithm
    for the browser<br />
    ... we need to decide first what to do with extensibility<br />
    ... then I don't see problem of having the algo closed to the
    ABNF definition<br />
    ... so Annex D will move up towards the formal grammar</p>

    <p class='phone'><cite>Erik:</cite> I will not make the parsing
    instructions normative, they are useful guidelines only</p>

    <p class='phone'><cite>Philip:</cite> if we need to valid the
    whole URI before, then parsers will be broken with version
    2</p>

    <p class='phone'><cite>Yves:</cite> yes, but if the new thing
    means already something you're already into trouble</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; ping?</p>

    <p class='phone'><cite>Yves:</cite> I agree</p>

    <p class='phone'>s/agrre/agree with Philip</p>

    <p class='phone'><cite>Raphael:</cite> could we just write a
    normative paragraph that states how the parser should behave
    ?</p>

    <p class='phone'><cite>Erik:</cite> a lot of test cases would
    need to be redefined</p>

    <p class='phone'><cite>Yves:</cite> I want to have everybody on
    the phone to agree what we want to do with extensibility</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; I would note that we
    can try to get agreement on the ML in the meantime</p><a name=
