+ XMPP allows for users and agents to find the identities and features
+ supported by other entities in the XMPP network through service discovery,
+ or "disco". In particular, the "disco#info" query type for <iq> stanzas is
+ used to request the list of identities and features offered by a JID.
+
+ An identity is a combination of a category and type, such as the 'client'
+ category with a type of 'pc' to indicate the agent is a human operated
+ client with a GUI, or a category of 'gateway' with a type of 'aim' to
+ identify the agent as a gateway for the legacy AIM protocol. See
+ <http://xmpp.org/registrar/disco-categories.html> for a full list of
+ accepted category and type combinations.
+
+ Features are simply a set of the namespaces that identify the supported
+ features. For example, a client that supports service discovery will
+ include the feature 'http://jabber.org/protocol/disco#info'.
+
+ Since clients and components may operate in several roles at once, identity
+ and feature information may be grouped into "nodes". If one were to write
+ all of the identities and features used by a client, then node names would
+ be like section headings.
+
+ Example disco#info stanzas:
+ <iq type="get">
+ <query xmlns="http://jabber.org/protocol/disco#info" />
+ </iq>
+
+ <iq type="result">
+ <query xmlns="http://jabber.org/protocol/disco#info">
+ <identity category="client" type="bot" name="SleekXMPP Bot" />
+ <feature var="http://jabber.org/protocol/disco#info" />
