Actually they are still abstract.

The XSl-FO 2 flow map does have support for flow mapping to multiple regions. > I do believe, however, that it would advance the art to revive and > complete XSL 2.0 along these lines.

The scales are weighted very heavily in favour of handling this level of complexity in HTML + CSS. As XML Activity Lead at W3C I'd have a really hard time in restarting the XSL-FO work, unless we had (1) implementers, and (2) users and (3) specification writers and (4) testers, and (5) funding. Even the print and page layout community group is pretty thin on the ground for people, although there's been some interesting work done there. The way to get what you want is probably to look at the CSS regions and flows stuff and send comments on it. It's true that XSL-FO adoption is on the rise, as publishers move to mixed PDF/print and ebook workflows. Other publishers who have been using XSl-FO for a while seem to be moving towards CSS, and although the claim that it's easier to find CSS expertise than XSl-FO expertise seems spurious (CSS-for-complex-print expertise is very very hard to find!) people do seem to find it compelling.
