Section title PDF 'keep with next'

[David Bocquet <david.bocquet@cosytec.com>]

Hi,

I'm using xsltproc and FOP to generate pdf output.
I don't know what to do to avoid having section title at the bottom of 
the page. Normally it should always "stay" with the following paragraph.
Is it a FOP problem, or am I missing a special parameter to handle this.

Thanks in advance.
