David Filip commented on XLIFF-72:
----------------------------------

I implemented and printed this yesterday as part of the proposed cos02. Please review and comment.
If you don't like this we can still amend and reprint, or get rid of the new informative text altogether and reprint.
Either way, we need to approve a cos02 in the meeting today..

> I am looking at this:
> http://docs.oasis-open.org/xliff/xliff-core/v2.1/xliff-core-v2.1.html#dir
> The possible values are lrt, rtl, and auto
> (with auto "determined heuristically, based on the first strong directional
> character in scope, see [UAX #9]").
> That is the same as the HTML dir attribute
>     https://www.w3.org/TR/2014/REC-html5-20141028/dom.html#the-dir-attribute
> But that is not enough, because the direction based on the first char
> results in bad rendering at times.
> So the HTML standard added <bdi> and <bdo>
> And also CSS needed to add even more control, with unicode-bidi:
>    https://www.w3.org/TR/CSS2/visuren.html#direction
> The values in the CSS2 standard seem to be normal, embed, bidi-override,
> inherit
> But more are coming: normal, embed, isolate, bidi-override,
> isolate-override, plaintext
> (https://www.w3.org/TR/css-writing-modes-3/#unicode-bidi)
> Mozilla and Chrome (and probably others will follow) already support these
> values:
>     https://developer.mozilla.org/en-US/docs/Web/CSS/unicode-bidi
> Chrome also supports "initial" (I don't check about Firefox)
> So the proposed values for dir seem insufficient.
> Kind of a pity to release something that is already outdated, without
> learning from what others did...
