FO only gives so many fixed (parametrised) layouts I don't think you
can say (which is I think What Patrick says in (lua)tex). Here is a
database dump of hundreds of text fragments, arrange them in a suitable
order to avoid bad page breaks and typeset the result. Obviously if you
are typesetting a text book, that isn't the kind of layout requiremt you
want, but it's not exactly uncommon either.

well of course it's an old model, I think the lack of feedback from the
renderer is the main issue anyone coming from TeX or or a TeX-like
system faces when looking at XSL-FO. It looks very much like TeX in its
page layout description and marks etc, except the inability to measure
typeset text makes it seem like working with both hands tied behind your
back at times. Page references/table of contents/indices are another
kind of feedback that is (or was last time I looked) hard to control.

That's not to say that FO should incorporate all the features of TeX,
there are some disadvantages to its "slightly" idiosyncratic programming
model, but
