[xsl] dynamic page break for tables

[Mathis Mörke <mathis.moerke@xxxxxxxxxxxxxx>]

Dear all,

I am experiencing an problem with keep-together.within-page. I work
with FOP Apache Version 0.95.
A short intro of my plan: I use xsl-fo as a style sheet for generating
reports out of Matlab. I'd like to have only one style sheet for 2
different types of reports. The main difference between both reports
are the layout of tables. The first report uses tables which fit to a
single page. The other report contains tables which can cause an
overflow. But thats not the problem. The crux is the following: The
table does not use <xsl:table> because FOP Apache does not support
captions of tables. To keep title, data and caption on a single page,
I use blocks and keep-together.within-page="always". But this does not
work in the second report because of an overflow. This is pretty clear
to me because of keep-together.within-page="always". Now, I am
searching for a method which combines both aspects. I would like to
avoid another template .. What I tried so far: Upgrade to version 1.0
to use integers for keep-together.within-page; avoid
keep-together.within-page and use keep-with-next with integers; ....
But it does not work ...
