<section1 topic='Business Rules' anchor='rules'>
<p>The following business rules apply:</p>
<ol start='1'>
<li><p>A sender SHOULD NOT include a request for message receipts when sending a message to the bare JID &LOCALBARE; of the recipient, only when sending to a full JID &LOCALFULL;.</p></li>
<li><p>A sender SHOULD NOT include a request for message receipts unless it knows (via &xep0030; or &xep0115;) that the intended recipient supports the protocol described herein or unless the use of message receipts is negotiated via &xep0155;.</p></li>
<li><p>A sender SHOULD include an 'id' attribute on the message so that the sender can properly track the receipt.</p></li>
<li><p>If receipts are desired, a sender SHOULD include a request for message receipts on all messages, no matter whether sending to the bare JID &LOCALBARE; of the recipient or the full JID &LOCALFULL;.</p></li>
<li><p>A sender MUST include an 'id' attribute on the message so that the sender can properly track the receipt.</p></li>
</ol>
<p>Naturally, message receipts can be combined with the rules specified in <cite>Advanced Message Processing</cite> (e.g., the deliver rule) for more complete reporting.</p>
</section1>
<section1 topic='Determining Support' anchor='disco'>
<p>If a sender wishes to request message receipts, it SHOULD first determine whether the intended recipient supports message receipts. This can be done directly via <cite>Service Discovery</cite> or indirectly via <cite>Entity Capabilities</cite>.</p>
<p>If an entity supports message receipts, it MUST report that by including a service discovery feature of "urn:xmpp:receipts" in response to disco#info requests:</p>
<example caption="Initial Service Discovery information request"><![CDATA[

<query xmlns='http://jabber.org/protocol/disco#info'>

<feature var='urn:xmpp:receipts'/>

</query>
</iq>
]]></example>
<p>A sender MAY include a request for message receipts even if it has not been able to determine if the intended recipient supports message receipts. This can be done directly via <cite>Service Discovery</cite> or indirectly via <cite>Entity Capabilities</cite>.</p>
</section1>
<section1 topic='Negotiation' anchor='neg'>
<p>Two entities MAY negotiate the use of message receipts for a given session using <cite>Stanza Session Negotiation</cite>. The parameter to be negotiated is named "urn:xmpp:receipts". Its use is illustrated in the following examples.</p>
