+  	Spring Integration also provides a special type router <classname>ErrorMessageExceptionTypeRouter</classname>  for routing 
+  	Error Messages (a Message with <code>payload</code> of type <classname>Throwable</classname>).
+    <classname>ErrorMessageExceptionTypeRouter</classname> is very similar to the <classname>PayloadTypeRouter</classname>. 
+    In fact they are almost identical. The only difference is that while <classname>PayloadTypeRouter</classname> navigates 
+    the instance hierarchy of an payload instance (e.g., <code>payload.getClass().getSuperclass()</code>) to find the most 
+    specific type/channel mappings, the <classname>ErrorMessageExceptionTypeRouter</classname> navigates the hierarchy of 
+    'exception causes' (e.g., <code>payload.getCause()</code>) to find the most specific <classname>Throwable</classname> type/channel mappings.
+  	</para>
