No. First, having recognized fantasai's proposal, I think that it should be carefully studied. (We might want to have *both*). Second, I have a number of comments on the proposal. See http://lists.w3.org/Archives/Public/www-style/2010Jun/0144.html Third, I am worried about the way BIDI and vertical writing are handled together. I guess that there are some fundamental differences between BIDI requirements and horizontal writing. Note that (1) Unicode has BIDI but not vertical writing, and that (2) HTML has @dir="ltr" and @dir="rtl" for years, but not @dir="ttb". I am afraid that I do not have deep understanding of BIDI requirements including the interactions among BIDI, users' preferences on directions, and relative margins, etc, and I do not know how these features are implemented by major browsers. Are we ready to provide a unified solution that aims to address both BIDI-related issues and vertical-writing- related issues? Cheers, Makoto
