    stream handler
        A callback function that accepts stanza objects pulled directly
        from the XML stream. A stream handler is encapsulated in a
        object that includes a :class:`Matcher <.MatcherBase>` object
        which provides additional semantics.

    event handler
        A callback function that responds to events raised by
        :meth:`.XMLStream.event`.

    stanza object
        Informally may refer both to classes which extend :class:`.ElementBase`
        or :class:`.StanzaBase`, and to objects of such classes.

        A stanza object is a wrapper for an XML object which exposes :class:`dict`
        like interfaces which may be assigned to, read from, or deleted.

    stanza plugin
        A :term:`stanza object` which has been registered as a potential child
        of another stanza object. The plugin stanza may accessed through the
        parent stanza using the plugin's ``plugin_attrib`` as an interface.

    substanza
        See :term:`stanza plugin`

    interfaces
        A set of keys defined on a :term:`stanza plugin`.

    stanza
        An XML payload sent over the XML stream, which is the root of XMPP.
        A stanza is either ``<iq/>``, ``<message/>`` or ``<presence/>``. Other
        elements are called nonzas.
