Are we talking about Docbook or FO here? XSL 1.0 has absolutely positioned block containers, and XSL 1.1 added the ability to flow content into multiple regions on the page. >> Typography is weak (at least with the open source tools available) > > FOP has poor typography and FO itself isn't really up to the standard of a > page layout tool but for many purposes it's good enough.

The absence of properties for kerning, etc., ties in with XSL-FO not specifying the line layout algorithm, which I would attribute partly to XSL 1.0 being meant to be used with multiple formatters, including being retrofitted onto pre-existing formatting engines (as it was), and partly to a philosophy that formatters should be able to implement the spec and still compete on features, so if you want better-looking paragraphs, you'd find the formatter that could do it. Developing software requires time and/or money (to fund the time). Open source software depends on people having the itch to solve that particular problem, not having more important claims on the time it would take to do it, and putting in the time to write the software. Commercial software companies use money to motivate the itch and the spending of time by their developers, and they use your money when they sell you the result as their motivation. To dismiss the open source implementations for not delivering better typography while being prepared to pay real money for commercial software ignores the possibility of pay real money to improve the open source implementations. If there was, say, a kickstarter.com project to improve the typography of FOP (which I am *not* setting myself up to do), would anyone here even make a pledge?

More to the point, with XSL-FO, it's never been clear whether things like signatures are part of its remit or something for a job control language to handle. For example, XSl-FO has only ever had a hazy notion of where the binding edge lies. But if you want to discuss things like that further, the best place at present would be the W3C Print and Page Layout Community Group [3], which anyone can join for free (and I happen to be the current Chair). > the 2.0 wishlist.

More input from the publishing industry, even on the Community Group, would be welcome.
