DOCBOOK-APPS: figure titles and imagedata spilt across pages

I would like to make sure that the title of a figure and the imagedata for that figure are not split across pages in my fo output.

For example in the following figure the title ends up at the bottom of one page while the imagedata ends up on the next.

<figure id="ccprobe-interface">
  <title>A schematic block diagram of the CCProbe Interface.</title>
  <mediaobject>
    <imageobject>
      <imagedata
fileref="images/png/ccprobe-interface-blockdiag.png" format="PNG" depth="200"/>
    </imageobject>
  </mediaobject>
</figure>
