+We can disable this feature using ``meta:interpolation``::
+
+  >>> print render("""\
+  ... <div xmlns="http://www.w3.org/1999/xhtml"
+  ...      xmlns:tal="http://xml.zope.org/namespaces/tal"
+  ...      xmlns:meta="http://xml.zope.org/namespaces/meta">
+  ...   <div meta:interpolation="false">
+  ...     ${'foo'}
+  ...   </div>
+  ... </div>""")
+  <div>
+    <div>
+      ${'foo'}
+    </div>
+  </div>
+
+The ``tail`` of an element does get intepolated depending oon
+it's parent::
+
+  >>> print render("""\
+  ... <div xmlns="http://www.w3.org/1999/xhtml"
+  ...      xmlns:meta="http://xml.zope.org/namespaces/meta">
+  ...   <div meta:interpolation="false">
