Sébastien:
To get around some performance issues
I was having with PDFs that were in the 500-1000 range, I currently have
it creating new page sequences every n rows. This results in some
strange results when it comes to page breaking so the method you mention
is _very_ intriguing. Could you please explain a bit more?

Hello,
We encountered similar issues a long time ago.
Because of the irregular structure of the page breaks, we used an approach
based on SAX filters (quite complex) located just before the FOP ContentHandler
aiming at transforming page-break into page sequences.
The SAX filter approach allowed us to keep low memory consumption.
eg.
<doc>
<page-sequence>
Data set 1
<break/>
Data set 2
<break/>
Data set 3
</page-sequence>
</doc>
transformed by SAX filters into :
<doc>
<page-sequence>
Data set 1
</page-sequence>
<page-sequence>
Data set 2
</page-sequence>
<page-sequence>
Data set 3
</page-sequence>
</doc>
Regards

We use a writting method that allows to cut heavy documents
in short
sequences.
So, each sequence is titled and we can insert a page-break before title.
It's especially an analytic approach, not a physical process,
that
consists in structuring and mapping the information.
