+   <p>In the following non-conforming snippet:</p>
+
+   <pre class=bad>...
+ &lt;form id="a"&gt;
+  &lt;div id="b"&gt;&lt;/div&gt;
+ &lt;/form&gt;
+ &lt;script&gt;
+  document.getElementById('b').innerHTML =
+     '&lt;table&gt;&lt;tr&gt;&lt;td&gt;&lt;form id="c"&gt;&lt;input id="d"&gt;&lt;/table&gt;' +
+     '&lt;input id="e"&gt;';
+ &lt;/script&gt;
+...</pre>
+
+   <p>The <a href=#form-owner>form owner</a> of "d" would be the inner nested
+   form "c", while the <a href=#form-owner>form owner</a> of "e" would be the
+   outer form "a".</p>
+
+   <p>This is because despite the association of "e" with "c" in the
+   <a href=#html-parser>HTML parser</a>, when the <code title=dom-innerHTML><a href=#dom-innerhtml>innerHTML</a></code> algorithm moves the nodes
+   from the temporary document to the "b" element, the nodes see their
+   ancestor chain change, and thus all the "magic" associations done
+   by the parser are reset to normal ancestor associations.</p>
+
+   <p>This example is a non-conforming document, though, as it is a
+   violation of the content models to nest <code><a href=#the-form-element>form</a></code>
+   elements.</p>
