Actually I meant it to describe what CSS already has (a few of) and to
try to distinguish semntic structures from (visual) presentational forms.

One could imagine a similar argument that says headings are paragraphs,
and then we have nothing but a sequence of glyphs on a page. All structure
is an artifice imposed on the text, but hopefully imposed because one can do
something useful with it. But I take your point about the essential fluidity
of presentational forms and would not argue that the current forms are in
some way primal.

Understood. Bi-directional hoizontal flow, for reasonable cases and with
scope for block and inline embeddings of different directionality is,
indeed, where we intend to go.

Yeah, if you like. And information wants to be free, and fruit flies
like a banana. Control can give you legibility, and I'm sure we will see
CSS used to produce utterly illegible pages (given trends in print
typography). But the first step in legibility is just being able to see
text in your own language, and many folks don't have that yet aside
