SVG in Docbook XML to PDF gives strange results

["Sanders, M." <MSA@ballastham.com>]

Hi all,

I am trying to figure out how to include SVG in my docbook XML 4.2 documents.
When I use the example from Bob Stayton's XSL book with a file called circle.svg:

<?xml version="1.0"?>
<svg xmlns="http://www.w3.org/2000/svg";>
<g style="fill-opacity:0.7; stroke:black; stroke-width:0.1cm;">
<circle cx="6cm" cy="2cm" r="100" style="fill:red;" transform="translate(0,50)" />
<circle cx="6cm" cy="2cm" r="100" style="fill:blue;" transform="translate(70,150)" />
<circle cx="6cm" cy="2cm" r="100" style="fill:green;" transform="translate(-70,150)"/>
</g>
</svg> 

Which is include in my docbook document as:
<...>
<sect1><title>Part1, Chapter 1, Section1</title>
<para>
Hello there!
</para>
<mediaobject id="MousePicture">
<imageobject>
<imagedata format="SVG" fileref="circle.svg"/>
</imageobject>
</mediaobject>
</sect1>
<...>

All I get at the location of the image is the upper left quarter of a red oval. I use fop-0.20.5, jimi-1.0.jar en the Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_01-b06) by Sun.
Anyone got an idea where my problem is?

Thanks,
