Thus, IQ interactions follow a common pattern of structured data exchange such as get/result or set/result (although an error can be returned in reply to a request if appropriate): .

The data content of the request and response is defined by the schema or other structural definition associated with the XML namespace that qualifies the direct child element of the IQ element (see Section 8.4), and the interaction is tracked by the requesting entity through use of the 'id' attribute.

Support for the XML stanza syntax and semantics defined in this specification is REQUIRED in XMPP client and server implementations.

These common attributes, as well as the basic semantics of the three stanza types, are defined in this specification; more detailed information regarding the syntax of XML stanzas for instant messaging and presence applications is provided in [XMPP‑IM], and for other applications in the relevant XMPP extension specifications.

included a legacy 'code' attribute, whose semantics have been replaced by the defined condition elements; information about mapping defined condition elements to values of the legacy 'code' attribute can be found in [XEP‑0086] The following conditions are defined for use in stanza errors.

It SHOULD NOT be used as the error message presented to a human user, but MAY be shown in addition to the error message associated with the defined condition element (and, optionally, the application-specific condition element).

Thus, the ) to extend the basic stanza syntax for the purpose of providing additional functionality. In addition, there are five common attributes for these stanza types. Three kinds of XML stanza are defined for the 'jabber:client' and 'jabber:server' namespaces: . However, a publishing client MAY also send a presence stanza with a 'to' attribute, in which case the server will route or deliver that stanza to the intended recipient. The semantics of IQ enable an entity to make a request of, and receive a response from, another entity. In general, a publishing client SHOULD send a presence stanza with no 'to' attribute, in which case the server to which the client is connected will broadcast that stanza to all subscribed entities.

Information about the current status of this document, any errata, and how to provide feedback on it may be obtained at ) if sending one of the latter errors would provide information about the intended recipient's network availability to an entity that is not authorized to know such information (for a more detailed discussion of presence authorization, refer to [XMPP‑IM] The requesting entity is not authorized to access the requested service because a prior subscription is necessary (examples of prior subscription include authorization to receive presence information as defined in [XMPP‑IM] The error condition is not one of those defined by the other conditions in this list; any error type can be associated with this condition, and it SHOULD NOT be used except in conjunction with an application-specific condition.
