          :param state: New presence state to broadcast
          :type state: :class:`aioxmpp.PresenceState`
          :param status: New status information to broadcast
          :type status: :class:`dict` or :class:`str`
          :param priority: New priority for the resource
          :type priority: :class:`int`
          :return: Stanza token of the presence stanza or :data:`None` if the
                   presence is unchanged or the stream is not connected.
          :rtype: :class:`~.stream.StanzaToken`
  
          If the client is currently connected, the new presence is broadcast
          immediately.
  
          `status` must be either a string or something which can be passed to
          the :class:`dict` constructor. If it is a string, it is wrapped into a
          dict using ``{None: status}``. The mapping must map
          :class:`~.LanguageTag` objects (or :data:`None`) to strings. The
          information will be used to generate internationalised presence status
          information. If you do not need internationalisation, simply use the
          string version of the argument.
