DOCBOOK-APPS: External-inlinegraphics

How do I get an external-graphic to behave like a inlinegraphic and not line
break before and after the graphic?

  <fo:external-graphic src="url({$filename})"
    content-width="{$width}" content-height="{$height}"
    width="auto" height="auto"/>

I also had to modify the style sheet and remove the url( ) to get the
graphics to resolve.

  <fo:external-graphic src="{$filename}"
    content-width="{$width}" content-height="{$height}"
    width="auto" height="auto"/>


I am using the following to create PDF files.
XML - 1.37 Docbook - Norm Walsh style sheets - XT - FOP 0.18.1 


Thanks in advance for your help,
