DOCBOOK-APPS: Controling image size with DSSSL

Hello,

I have never been able to use the width attribute of imagedata.

How comes the following piece of code do not have any effect on PDF 
output? The image remains the same size as if the width attribute were 
not used.

-----------------------------------------------
<imageobject>
   <imagedata fileref="test.pdf" format="EPS" width="10cm" scalefit="1"/>
</imageobject>
-----------------------------------------------

This is processed with openjade-1.3.1 through dsssl 1.77. The scale 
feature works though.

Camille.
