DOCBOOK-APPS: xsl-fo, 1.48 stylesheets

[Dave Pawson <daveP@dpawson.freeserve.co.uk>]

In the output I see

<fo:block space-before.minimum="0.8em" space-before.optimum="1em" 
space-before.maximum="1.2em" font-family="Courier" font-size="9pt" 
wrap-option="no-wrap" text-align="start" white-space-collapse="false" 
linefeed-treatment="preserve">
         writing-mode="tb-rl"&gt;</fo:block>
                   <span class="co">
                      <img src="images/3.png" alt="(3)"/>
                   </span>
                   <fo:block space-before.minimum="0.8em" 
space-before.optimum="1em" space-before.maximum="1.2em" 
font-family="Courier" font-size="9pt" wrap-option="no-wrap" 
text-align="start" white-space-collapse="false" linefeed-treatment="preserve">


Element span?

Something leaking from the html stylesheets?
