+    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>.
+
+    Example legacy error stanzas:
+        <error xmlns="jabber:client" code="501" type="cancel">
+          <feature-not-implemented
+                xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" />
+        </error>
+
+        <error code="402" type="auth">
+          <payment-required
+                xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" />
