+    XEP-0086: Error Condition Mappings
+
+    Older XMPP implementations used code based error messages, similar
+    to HTTP response codes. Since then, error condition elements have
+    been introduced. XEP-0086 provides a mapping between the new
+    condition elements and a combination of error types and the older
+    response codes.
+
+    Also see <http://xmpp.org/extensions/xep-0086.html>.
+
+    Configuration Values:
+        override -- Indicates if applying legacy error codes should
+                    be done automatically. Defaults to True.
+                    If False, then inserting legacy error codes can
+                    be done using:
