Section titles bottom of a print page when there is as subtitle

[Peter Fleck <peterfleck@gmail.com>]

Hi,

How do you stop section titles being at the bottom of a print page when 
there is as subtitle? ie. If there isn't space for at least one or two 
lines for the following paragraph the section title moves to the 
following page.

Here's the xml:

<section>
 <info>
    <title>The Title</title>
    <subtitle>The Subtitle</subtitle>
</info>
 <para>....

So at the bottom of the page is the <title> followed by the <subtitle> 
and then the <para> starts on a new page.

I'm using 1.79.2 with Apache FOP 2.2.

I know I can use <?dbfo-need height="..." ?> but would rather not have 
to put it in XML if there is an XSL solution.

Thanks,

Peter
