+    <p><span class=updated>[2015-07-01]</span> An element with
+    'position: fixed', unlike one with 'position: absolute',
+    <em>always</em> establishes a new stacking context. (This is
+    different from 'position: absolute', where 'z-index' determines if
+    the element establishes a stacking context.)
 
+    <p>Change the definition of 'auto' in <a
+    href="visuren.html#z-index" >&ldquo;9.9.1 Specifying the stack
+    level: the 'z-index' property&rdquo;</a> as follows:
+
+    <blockquote>
+     <dl>
+      <dt><strong>auto</strong> <dd>The stack level of the generated
+       box in the current stacking context is 0. <del>The box does not
+       establish a new stacking context unless it is the root
+       element.</del> <ins>[TBD] </ins>
+     </dl>
