How to store a background image of a shape in flat format

[Regina Henschel <regina.henschel@libreoffice.org>]

Hi all,

If you use the packed format you can use a folder 'Pictures' (or 'media' 
in case of PowerPoint) with an image e.g. XYZ.png.

And in <office:styles> you have
<draw:fill-image draw:name="foo" xlink:href="Pictures/XYZ.png" 
xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad"/>

But how do you store the image in flat format? In contrast to a 
<style:background-image> the <draw:fill-image> has no child element 
<office:binary-data>.
