   title="">x</var> is said to be a <dfn>WebVTT file using only nested
   cues</dfn>.</p>
 
+  <div class="example">
+
+   <p>The following example matches this definition:</p>
+
+  <pre>WEBVTT
+
+00:00.000 --> 01:24.000
+Introduction
+
+00:00.000 --> 00:44.000
+Topics
+
+00:44.000 --> 01:19.000
+Presenters
+
+01:24.000 --> 05:00.000
+Scrolling Effects
+
+01:35.000 --> 03:00.000
+Achim's Demo
+
+03:00.000 --> 05:00.000
+Timeline Panel</pre>
+
+   <p>Notice how you can express the cues in this WebVTT file as a
+   tree structure:</p>
+
+   <ul>
+    <li>WebVTT file
+     <ul>
+      <li>Introduction
+       <ul>
+        <li>Topics
+        <li>Presenters
+       </ul>
+      </li>
+      <li>Scrolling Effects
+       <ul>
+        <li>Achim's Demo
+        <li>Timeline Panel
+       </ul>
+      </li>
+     </ul>
+    </li>
+   </ul>
+
+   <p>If the file has cues that can't be expressed in this fashion,
+   then they don't match the definition of a <span>WebVTT file using
+   only nested cues</span>. For example:</p>
+
+  <pre>WEBVTT
+
+00:00.000 --> 01:00.000
+The First Minute
+
+00:30.000 --> 01:30.000
+The Final Minute</pre>
+
+   <p>In this ninety-second example, the two cues partly overlap, with
+   the first ending before the second ends and the second starting
+   before the first ends. This therefore is not a <span>WebVTT file
+   using only nested cues</span>.</p>

   <p>A <dfn>WebVTT timestamp</dfn> representing a time in seconds and
   fractions of a second is a <span>WebVTT timestamp</span>
   representing hours <var
