    I was simply suggesting that there may be issues there to consider, but
    not necessarily implying that the bidi algorithm needed to address in
    any way interactions between boustrophedon and non-boustrophedon text. I
    *could not possibly* suggest that until I had some idea of what the
    expected behaviour should be. I'm not aware of there being any
    conventionally-defined behaviour for interaction between strong LTR or
    RTL text and boustrophedon text. The requirements have to be defined
    before a solution can be architected. And as you go on to point out...

    it's not obvious that requirements do exist.
