(See the dominant-baseline and alignment-baseline properties in [CSS-INLINE-3].)
The links however points to the SVG spec:
https://www.w3.org/TR/SVG/text.html#DominantBaselineProperty
https://www.w3.org/TR/SVG/text.html#AlignmentBaselineProperty
I think they should link to:
https://drafts.csswg.org/css-inline/#dominant-baseline-property
https://drafts.csswg.org/css-inline/#alignment-baseline-property
BTW, shouldn't all outgoing links in a draft spec point to other draft specs?
And only "freeze" the outgoing links to TR specs once the spec itself is TR?
(As an implementor, I rarely want to see anything but the latest information,
which is in the draft specs, so it's a bit annoying to be led astray when
clicking links to other specs.)
