<p>If you want to store different types of embedded documents in the same field,
you can simply omit the <code class="docutils literal"><span class="pre">targetDocument</span></code> option:</p>
<div class="configuration-block">
<ul class="simple">
<li><em>PHP</em><div class="highlight-php"><div class="highlight"><pre><span class="cp">&lt;?php</span>

</div>
</li>
</ul>
</div>
<p>Now the <code class="docutils literal"><span class="pre">$tasks</span></code> property can store any type of document! The class name will
be automatically stored in a field named <code class="docutils literal"><span class="pre">_doctrine_class_name</span></code> within
the embedded document. The field name can be customized with the
<code class="docutils literal"><span class="pre">discriminatorField</span></code> option:</p>
