We believe that this was resolved in another issue: http://lists.w3.org/Archives/Public/www-svg/2008Oct/0070.html > Also given "In SVG Tiny 1.2, vertical writing is not supported." > in http://www.w3.org/TR/SVGMobile12/text.html#TextLayout that > last sentence should be removed. As mentioned in my previous reply, because we do not forbid SVG 1.2 Tiny UAs to support vertical text, and because we want to keep consistency with our other specs, we decided not to remove the last bullet point. But we do agree that it could be confusing for readers (though it's mentioned in the prefatory material), so we added an explanatory note to the bullet point: [[ * For top to bottom vertical (vertical Chinese, etc): start is top and end is bottom (Note: SVG Tiny 1.2 does not mandate the support of vertical text.) ]] You can see the changes inline here: http://dev.w3.org/SVG/profiles/1.2T/publish/text.html#TextAlignProperty Please let us know if this changes satisfy your comment.
