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 :term:`Matcher` object, and which provides
additional semantics. For example, the ``Waiter`` handler wrapper
blocks thread execution until a matching stanza is received.
event handler
A callback function that responds to events raised by
``XMLStream.event``. An event handler may be marked as
threaded, allowing it to execute outside of the main processing
loop.
stanza object
Informally may refer both to classes which extend ``ElementBase``
or ``StanzaBase``, and to objects of such classes.
A stanza object is a wrapper for an XML object which exposes ``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.
