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