[csswg-drafts] [css-inline][css-writing-modes] definition of the central baseline

== [css-inline][css-writing-modes] definition of the central baseline

Rescued from an old mail:

The css-inline spec 
[defines](https://drafts.csswg.org/css-inline/#valdef-dominant-baseline-central)
 `dominant-baseline: central` as:

> Use the central baseline (halfway between the ascent and descent).

Is "halfway between the ascent and descent" a usable (or correct) 
definition in vertical writing modes when text-orientation is mixed or
 upright?
