Docbook 5.0 and imageobjectco

Hello,

Is imageobjectco with area and coords work in docbook 5.0. As I  
remember it doesn't work well with previous version, but now ?

<http://www.docbook.org/tdg5/en/html/imageobjectco.html>
This exemple work put I tried to use it in for mu PDF output and It  
seems not working.

<figure>
	<info><title>Les informations d'un enregistrement A</title></info>
	<mediaobject>
		<imageobjectco>
			<areaspec unit="calspair">
				<areaset xml:id="record" coords="">
					<area xml:id="record_name" coords="560 260"/>
				</areaset>
			</areaspec>
			<calloutlist>
				<callout arearefs="record_name">Nom de la machine</callout>
				</calloutlist>
			<imageobject>
				<imagedata fileref="images/Leopard/DNS/AddRecord2.pdf"  
align="center" format="PDF" scalefit="1" scale="50"/>
			</imageobject>
		</imageobjectco>
	</mediaobject>
</figure>

In fact I don't have any callout icon on my picture and no callout in  
a list after the image.

Thanks for your help,

Jacques
