Adding a floating image

[ashelton3]

Hi,

I am unable to place an image in my paragraph so that the paragraph text flows around it. I am using saxon and the XEP processor. Where are the values of the dbfo documented?
Here's my code:

<sidebar>
<?dbfo sidebar-width="335px"?>
<?dbfo float-type="left"?>
<para>
<imagedata fileref="img/david-bowie-001.jpg" scale="100" scalefit="1"
  width="315px" depth="445px" contentwidth="315px" contentdepth="445px"/>
</para>
</sidebar>
