    3.1 WD Template:

    close ACTION-33

    <trackbot> ACTION-33 Start the template of the document closed

    Raphael has prepared a template



    scribe: will check in html files
    ... will send reminder on who is responsible for which section

    Erik suggests to add hard deadlines to the sections, so we can go
    towards our milestones

    Raphael suggests that a week per sections may be do-able because
    it's a straight copy from the wiki

    Erik agrees

    scribe: asks, when we want the document to be posted/published, so
    we can work backwards towards deadlines

    Raphael says that our first working draft was due by end of January

    scribe: we should have it all ready by mid march

    Conrad will post more comments

    close ACTION-41

    <trackbot> ACTION-41 Rewrite Syntax in ABNF based on RFC4234 closed

    Yves has posted a ABNF

    Michael suggested to write the generic rule at the top and go into
    more detail further down

    Yves reckons this is a matter of taste

    Yves will add more details to link it to the original URI spec

    Raphael thinks we decided to have either a named fragment or a
    combination of the others



    scribe: this is not represented right now

    Yves thinks this is hard to capture in the production rule, and
    better to describe in text

    Let's give this a try and see what comments we get back
