Thanks for punting that to the ML. Wrt the paragraph beginning "In general...", it has been revised: # In CSS, the paragraph embedding level must be set (following rule HL1) # according to the direction property of the paragraph’s containing # block rather than by the heuristic given in steps P2 and P3 of the # Unicode algorithm. There is, however, one exception: when the # computed unicode-bidi of the paragraph’s containing block is # 'plaintext', the Unicode heuristics in P2 and P3 are used as # described in [UAX9], without the HL1 override. Wrt referring to the HL* rules, the bidi spec does not appear to require such references, only that modifications to the algorithm conform to those rules. However I have added the references as you request to help clarify the intent. Wrt using "must" everywhere, whether one agrees or disagrees with the style, it is not a habit of the CSS specs to do so, and statements without the modifier are nonetheless normative per http://www.w3.org/TR/css3-writing-modes/#conventions
> is "the bidi control codes assigned to the end" defined anywhere? Yes, the control codes are defined under the various unicode-bidi values [..] But I agree that some sort of reference is needed.
Since this sentence is only a few paragraphs below the section that defines them, I haven't added a link. But all of them are now talking about rule HL3, so this will help create that correspondance.
I now realize, however, that the spec does not make it 100% clear for isolate-override whether it "combines" the isolate on the outside of the override or vice-versa.
This is now specified explicitly. Comment #2 is handled separately, see thread at http://lists.w3.org/Archives/Public/www-style/2014Feb/0267.htm Updated ED: http://dev.w3.org/csswg/css-writing-modes/ Please let me know if this sufficiently addresses the comment. ~fantasai _______________________________________________ Unicode mailing list Unicode@unicode.org http://unicode.org/mailman/listinfo/unicode
