[css3-writing-modes] Character's intrinsic orientation and text-orientation property (was referring to Unicode

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.

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.
