There are plenty of commercial tools using XSL-FO and producing reams
of document conversions in professional publishing scenarios. So although
it isn't visible on the web, the technology is well entrenched, just not on
your phone...

It is entirely likely that those tools will wish to retain compatibility with CSS3
writing modes for many reasons.

Head/Foot as explained by the Japanese readers doesn't adequately
address vertical layout in Japanese text where it's still the top/bottom
of the page.

before/after clash with ::before/::after which is unfortunate. But aliasing
just creates further mess where the same names have different meaning
depending on context.

I just went to the paint shop and the guy there suggested 'pre/post' as
suitable terms for aliasing. pre -> before; post -> after kind of like in postscript.;-)
