<div class="refsect1" title="Description"><a name="id1457552"></a><h2>Description</h2>
<p>This template takes a list of media objects (usually the
children of a mediaobject or inlinemediaobject) and determines
the "right" object. It returns the position of that object
to be used by the calling template.</p>
<p>If the parameter <a href="../html/use.role.for.mediaobject.html"><em class="parameter"><code>use.role.for.mediaobject</code></em></a>
is nonzero, then it first checks for an object with
a role attribute of the appropriate value. It takes the first
of those. Otherwise, it takes the first acceptable object
through a recursive pass through the list.</p>
<p>This template relies on a template named "is.acceptable.mediaobject"
to determine if a given object is an acceptable graphic. The semantics
of media objects is that the first acceptable graphic should be used.
</p>
<p>If no acceptable object is located, no index is returned.</p>
