[oXygen-user] DocBook image scale issue

[Timothy Reaves]

	I have this bit of code:
<mediaobject>
	<imageobject>
		<imagedata fileref="figures/figures.png" format="PNG" scale="50"/>
	</imageobject>
</mediaobject>

I believe this is correctly specified as per the specs.  However,  
when I generated my PDF, the image was displayed as if I had not used  
scale at all (which is actually a little larger that 100%, which is  
why I want to use scale).

	When I turn of FOP output, I see this:
[ERROR] Error in content-width property value '50%':  
org.apache.fop.fo.expr.PropertyException: No conversion defined
[ERROR] Error in content-height property value '50%':  
org.apache.fop.fo.expr.PropertyException: No conversion defined

Any ideas as to what I've done incorrectly?
