<p>When an entity wants to send a non-error message to be handled by all a user's IM-NG clients they will send it to the user's bare JID, which the receiving server then MUST send to all the contact's IM-NG resources, and the sending server must reflect to all the user's IM-NG resources.</p>

<p>When an entity wants to send a non-error message to be received exclusively by a single resource, they include an &lt;im-ng xmlns='urn:xmpp:im-ng:0'&gt; element in the message. An IM-NG server receiving this MUST then send it to only the specified resource, if available, or respond with an error consistent with RFC-6121 ("return an error stanza to the sender, which SHOULD be &lt;service-unavailable/&gt;").</p>

<section1 topic='Business Rules' anchor='rules'>
<p>Any message of normal type, or type 'chat', 'groupchat' or 'headline' sent to a bare JID is distributed to all IM-NG clients (error messages sent to the bare JID are in response to server-generated stanzas, and so are not routed to clients).</p>
<p>A message of type error, sent to a full JID without an &lt;im-ng xmlns='urn:xmpp:im-ng:0'&gt; element is to be distributed to all IM-NG clients</p>
<p>Any message that is routed to all IM-NG clients is stored in the MAM archive, where available, and any message that would not be routed to all IM-NG clients is not stored in the MAM archive</p>
<p>In order for interoperatility with other entities (contacts, remote servers etc.) that don't support IM-NG, old-style full-JID messages also need to be handled. When a server receives a message with type other than normal or 'chat' that does not contain an &lt;im-ng xmlns='urn:xmpp:im-ng:0'&gt; element are routed by the above rules as if they were sent to the bare JID</p>

<p>A client activating IM-NG MUST NOT also activate Carbons.</p>
<p>An IM-NG client SHOULD send all IM-related messages to bare JIDs (as full-JID messages would not be distributed appropriately).</p>
<p>An IM-NG client SHOULD ignore any IM-related messages that are sent to a full-JID with an &lt;im-ng xmlns='urn:xmpp:im-ng:0'&gt; element (see Security Considerations).</p>
<p>When reflecting an IM-NG client's outbound bare-JID messages, the server SHOULD reflect the archived version (i.e. after any transforms have taken place).</p>
