<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.
