        """
        Given that XMPP is based on TCP connections, it is possible for the
        underlying connection to be terminated without the application's
        awareness. Ping stanzas provide an alternative to whitespace based
        keepalive methods for detecting lost connections.

        Example ping stanza:
        ::

            <iq type="get">
              <ping xmlns="urn:xmpp:ping" />
            </iq>
        """

        namespace = 'urn:xmpp:ping'
        plugin_attrib = 'ping'
