     <p>As Jabber/XMPP technologies have matured, the need for a generic publish-subscribe ("pubsub") mechanism has arisen in a number of domains. These include (but are not limited to): news feeds and content syndication, extended presence, avatar management, shared bookmarks, auction and trading systems, online catalogs, workflow systems, network management systems, NNTP gateways, profile management, and event notification.</p>
-    <p>In all of these domains, it is desirable for data communication to follow the classic "publish-subscribe" or "observer" design pattern: a person or application publishes information, and an event notification (without or without payload) is broadcasted to all authorized subscribers. In general, the relationship between the publisher and subscriber is mediated by a service that receives publication requests, broadcasts event notifications to subscribers, and enables privileged entities to manage lists of people or applications that are authorized to publish or subscribe. In most pubsub services, the focal point for publication and subscription is a "topic" or "node" to which publishers send data and from which subscribers receive notifications. Additionally, some nodes may also maintain a history of events and provide other services that supplement the pure pubsub model.</p>

     <p>This document defines a single, cohesive, generic protocol that all forms of pubsub can use. While compliant implementations are not required to implement all of the features defined herein, this document addresses most use cases that may be requested of a pubsub service. (For information about which features are required and which are recommended or optional, consult the <link url='#features'>Feature Summary</link>.) Other specifications may define "subsets" or "profiles" of publish-subscribe for use in specialized contexts, but such profiles are out of scope for this document.</p>
