    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:
                        iq['error']['legacy']['condition'] = ...
