I understand and agreed with your suggestion for better wording referring to Unicode in this mail[1], but for this specific example, I think there's some misunderstanding between us. > In the case of the 'text-orientation' property, the reasons for this > are evidenced by the issue noted at the end of the property description: > > "Issue: Need to define handling of EAW Ambiguous (A) symbols and punctuation." > > In other words, the decision as to whether to rotate the glyphs for > a given character in vertical text needs to be more clearly specified > since this is *not* explicitly covered as part of the text of UAX11. The description of the 'text-orientation' property[2] doesn't say "just use UAX11"; instead, it defines an algorithm using properties defined in UAX11. It was once discussed in www-style[3], but here's a copy of the pseudo algorithm: IF ScriptOrientation=Translate || (EAW=F|W) Always upright ELIF ScriptOrientation=Rotate # All chars are EAW=N Always sideways ELIF ScriptOrientation=Horizontal # EAW=F|W are already excluded by first IF Sideways for ''vertical-right'', upright for ''upright'' ELIF # Script=Common|Inherited|Unknown IF EAW=H|N|Na Sideways ELSE # EAW=A ... The "..." part is where the issue points to, and the one we discussed once in www-style[3]. I hope this matches to your original intention, except that we should use your suggested description for the Unicode property names.
