45 <p>XMPP components are used for long through &xep0114;, but are quite limited: they have a restricted access to other entities data, similar to what a client can do. This is sufficient for components like gateways, but very limiting for more complex components like a PubSub service. The goal of this XEP is to allow a component to have a "privileged" status, and access an entity data with the same privileges than the entity itself, that means send and receive IQ stanzas on its behalf.</p>
