Most publications need more than the six option you mention. Here's a picture
of the first three publications I grabbed from my shelf:


In other common publications, like Lonely Planet books or The
Economist and you will find more examples.

The specification should not say anything about dialog boxes. But
implementation may regard settings from UI dialogs as part of the user
(or browser) style sheet. So it has its place in the cascade and
therefore a formal model for resolving conflicts.

In your preferred solution, how would you express this?:

   @page { @top-center { content: element(header) }}
   @page :left { @top-left { content: counter(page) }}
   @page :right { @top-right { content: counter(page) }}
   header { position: running(header) }

This is fairly typical styling at a level found in most novels. Both
before 2002, in 2002, and after 2002 :-)

Or this?:


One leading publisher, Hachette, uses CSS to print and publish
hundreds of books on paper every year. Here's a presentation
describing their setup:


Naturally, they depend on css3-page, margin boxes and statements like
the above to achieve this.

And implementations. Here's a test page for margin boxes along with
output from three formatters:


Antennahouse and Prince are interoperable. Weasyprint almost so. 

Given all this, I think it should be a priority for the WG to advance
the currently described functionality to REC.
