Ok, the trouble is that mediaobject doesn't have exactly the same semantics
as graphic. The whole point of mediaobject was to allow documents to specify
multiple alternative presentations. You have:

    <mediaobject>
      <imageobject>
	<imagedata fileref="fig1">
      </imageobject>
      <textobject>
	<literallayout>
+---------+
|    A    |
+---------+
	</literallayout>
      </textobject>
      <textobject>
	<phrase>My first image</phrase>
      </textobject>
    </mediaobject>

And you're expectation is that the stylesheets will use
%graphic-default-extension% to augment 'fig1' appropriately. What you
"should" have in your document is:

    <mediaobject>
      <imageobject>
	<imagedata fileref="fig1.eps">
      </imageobject>
      <imageobject>
	<imagedata fileref="fig1.png">
      </imageobject>
      <textobject>
	<literallayout>
+---------+
|    A    |
+---------+
	</literallayout>
      </textobject>
      <textobject>
	<phrase>My first image</phrase>
      </textobject>
    </mediaobject>

With this markup, the print and HTML stylesheets will make the right
selections.

Having said that, I've also fixed it so that a single imageobject with a
filename that does not have an extension works as you expected :-)

                                        Be seeing you,
                                          norm
