+ XMPP's <presence> stanza allows entities to know the status of other
+ clients and components. Since it is currently the only multi-cast
+ stanza in XMPP, many extensions add more information to <presence>
+ stanzas to broadcast to every entry in the roster, such as
+ capabilities, music choices, or locations (XEP-0115: Entity Capabilities
+ and XEP-0163: Personal Eventing Protocol).
+
+ Since <presence> stanzas are broadcast when an XMPP entity changes
+ its status, the bulk of the traffic in an XMPP network will be from
+ <presence> stanzas. Therefore, do not include more information than
+ necessary in a status message or within a <presence> stanza in order
+ to help keep the network running smoothly.
+
+ Example <presence> stanzas:
+ <presence />
+
+ <presence from="user@example.com">
+ <show>away</show>
+ <status>Getting lunch.</status>
+ <priority>5</priority>
+ </presence>
+
+ <presence type="unavailable" />
+
+ <presence to="user@otherhost.com" type="subscribe" />
+
+ Stanza Interface:
+ priority -- A value used by servers to determine message routing.
+ show -- The type of status, such as away or available for chat.
+ status -- Custom, human readable status message.
+
+ Attributes:
+ types -- One of: available, unavailable, error, probe,
+ subscribe, subscribed, unsubscribe,
+ and unsubscribed.
+ showtypes -- One of: away, chat, dnd, and xa.
+
+ Methods:
+ reply -- Overrides StanzaBase.reply
+ setShow -- Set the value of the <show> element.
+ getType -- Get the value of the type attribute or <show> element.
+ setType -- Set the value of the type attribute or <show> element.
+ getPriority -- Get the value of the <priority> element.
