Why not use a new role value?  "tex"?  Or "latex"?  Then you could add
a new <imageobject> for use by DB2LaTeX. 

The new use of role was done without any changes to the DTD, so the
value of role is still defined to be #CDATA.

Here's an example of how I currently use this approach:

	<mediaobject>
	  <imageobject role="html">
	    <imagedata fileref="images/press_enter.png" format="PNG"/>
	  </imageobject>
	  <imageobject role="fo">
	    <imagedata fileref="images/press_enter.png" format="PNG"
	    depth="5cm" scalefit="1"/>
	  </imageobject>
	</mediaobject>

If I were to use this with DB2LaTeX, as well as the current HTML and
XSL:FO, I would add an extra <imageobject>, with scaling and role
"latex", ie.:

	<mediaobject>
	  <imageobject role="html">
	    <imagedata fileref="images/press_enter.png" format="PNG"/>
	  </imageobject>
	  <imageobject role="fo">
	    <imagedata fileref="images/press_enter.png" format="PNG"
	    depth="5cm" scalefit="1"/>
	  </imageobject>
	  <imageobject role="latex">
	    <imagedata fileref="images/press_enter.png" format="PNG"
	    depth="5cm" scalefit="1"/>
	  </imageobject>
	</mediaobject>
