    Thank you for providing many useful and interesting links.

    FYI, three list styles for Ethiopic scripts were implemented in Mozilla
    a long time ago. One of them was Ethiopic numeric list style. All three
    styles are in CSS3 draft.
    (http://bugzilla.mozilla.org/show_bug.cgi?id=102252).

    BTW, isn't this covered in TUS 3.0 section 11.1 as well as in
    TUS 4.0 section 12.1 (p. 323 - p. 324) ?
