In this example, the 'jid' specifies that the roster entry 'romeo@montague.net' is a member of a metacontact. The 'tag' provides a key for a metacontact; in this example all metacontacts with a tag of 'd93nov' (across all accounts) refer to the same entity. The 'order' denotes the priority of this Jid over other Jids within the metacontact, with it being preferable to use Jids with higher priority (this is roughly analogous to the 'priority' on presence stanzas when a Jid has multiple online resources in XMPP).

<p>Although it is unavoidable that multiple contacts within a metacontact MAY have the same order (due to potentially unavailable information from other accounts), clients SHOULD NOT apply the same order to multiple members of the same metacontact where it is possible to avoid it.

<p>To limit the extent of the presence leak, the receiving entity SHOULD send only bare presence without the XMPP &PRIORITY;, &SHOW;, or &STATUS; element. Unfortunately, this has two implications:</p>
<ol>
<li><p>The initiating entity cannot know which of the receiving entity's resources is more likely to engage in communication.

<li><p>Establishment of a session might be delayed (e.g., because in Jingle it is desirable to start negotiating candidates as soon as possible but a user interface that prompts the receiving entity to explicitly approve of divulging presence will tend to a delay in call setup).

<li>A &MESSAGE; is eligible for carbons delivery if it is of type "error" and sent in response to a &MESSAGE; that was itself eligible for carbons delivery (Note that as this would require message tracking and correlation on the server, it is unlikely to be generally appropriate for most implementations).</li>
<li>A &MESSAGE; is not eligible for carbons delivery if it is determined to have been sent by a MUC room or service, even if it would be otherwise eligible (this also includes private messages from MUC participants).</li>

<p>Possible delivery rules:</p>
<ul>
<li>A &MESSAGE; is eligible for carbons delivery if it is of type "chat".</li>
<li>A &MESSAGE; is eligible for carbons delivery if it is of type "normal" and it contains a &lt;body&gt; element.</li>
<li>A &MESSAGE; is eligible for carbons delivery if it is of type "error" and sent in response to a &MESSAGE; that was itself eligible for carbons delivery (Note that as this would require message tracking and correlation on the server, it is unlikely to be generally appropriate for most implementations).</li>

<li>A &MESSAGE; is not eligible for carbons delivery if it does not meet any of these criteria.</li>
</ul>
<p>As this is a implementation detail of servers, clients MUST NOT rely on the server implementing a particular set of rules for which messages are eligible for Carbons delivery.</p>
<p>Future specifications may have more precise requirements on which messages need to be eligible for carbons delivery; such future specifications will provide their own discovery and negotiation mechanisms, such that a client negotiating Carbons using the protocol defined in this specification will cause the server to consider messages eligible for Carbons delivery based on the requirements described herein.</p>
<p>Note: previous versions of this specification limited eligible messages to those of type "chat" - however, this was generally found to be inadequate due to the proliferation of type "normal" messages used in instant messaging.</p>

However, this assumption introduces a single point of failure for the conference room, since if occupants at a using domain lose connectivity to the hosting domain then they also lose connectivity to the room. In some deployment scenarios (and even on the open Internet) this behavior is suboptimal. Therefore, this document attempts to define a technology for distributing MUC rooms across multiple services.</p>

<p>There are various spim protection methods exist in XMPP: &xep0016;, &xep0158;, &xep0191;, &xep0268; and &xep0275;. But they may not be sufficient enough:
<ul>
<li>&xep0016; and &xep0191; define blocking mechanism only which is not always appropriate.</li>
<li>&xep0158; interacts badly with automated software such as gateways.</li>
<li>&xep0268; implies trusted network of servers.</li>
<li>&xep0275; concentrates on ranking only.</li>
</ul>
Service administrators might want to deploy server-based spim recognition software to fill in the gaps. However, every automated spim recognition suffers from <em>false positives</em> - situations where a stanza incorrectly qualified as spim. To avoid them, a spim filter doesn't block suspicious stanza, but marks it and sends to a client in a regular manner. A client software doesn't need to interrupt a user when processing such marked stanzas: for example, it may put them silently in "SPAM" folder, so a user can look through them at any time later. Furthermore, a spim filter may take user's experience into account. When a user receives an unsolicited stanza, he or she can mark it as spim. In this case a client software sends an automatic complaint to a server-based spim filter. This specification deals with both cases. Thus, in contrast to &xep0159;, it doesn't introduce any spim blocking techniques. Also, the various spim recognition procedures that may be employed by the server are beyond the scope of this document.
