+<para>A mediaobject may contain several objects such as imageobjects.
+If the parameter <parameter>use.role.for.mediaobject</parameter> is
+non-zero, then the <literal>role</literal> attribute on
+<tag>imageobject</tag>s and other objects within a
+<tag>mediaobject</tag> container will be used to select which object
+will be used.  If one of the objects has a role value that matches the
+<parameter>preferred.mediaobject.role</parameter> parameter, then it
+has first priority for selection.  If more than one has such a role
+value, the first one is used.
+</para>
+<para>
+See the <parameter>use.role.for.mediaobject</parameter> parameter
