32 * @file jpacket.c
33 * @brief a jpacket is a wrapper around an xmlnode that contains an XMPP stanza
34 *
35 * A jpacket adds some variables to an xmlnode that contains a stanza, so that
36 * jabberd is able to cache information on the stanza type (message, presence, iq)
37 * that is contained in this jpacket and to further classify the presence stanzas.
38 * It also adds some pointers to important data inside the xmlnode, that has
39 * to be accessed often (e.g. sender and receiver of a stanza).
