<section1 topic='Introduction'>
|
|
<p>The Jabber protocols have long included a method for sending roster items to another entity. This method makes use of the 'jabber:x:roster' namespace and has been documented variously in Internet-Drafts and elsewhere. Because this protocol is not required by &rfc2779;, the 'jabber:x:roster' namespace was removed from &xmppim;. This specification fills the void for canonical documentation.</p>
|
|
<p><em>NOTE WELL: This document has been superseded by &xep0144;.</em></p>

|
<section1 topic='Definition'>
|
|
<p>The 'jabber:x:roster' namespace (which is not to be confused with the 'jabber:iq:roster' namespace) is used to send roster items from one Jabber entity to another. A roster item is sent by adding to the <message/> element an <x/> child scoped by the 'jabber:x:roster' namespace. This <x/> element MUST contain at least one <item/> child elements (one for each roster item to be sent).</p>
|
|
<p>Each <item/> element may possess the following attributes:</p>
|
|
<ul>
|
|
<li><strong>jid</strong> -- The Jabber Identifier of the contact being sent. This attribute is REQUIRED.</li>
|
|
<li><strong>name</strong> -- A natural-language nickname for the contact. This attribute is OPTIONAL.</li>
|
|
</ul>
|
|
<p>Each <item/> element MAY also contain one or more <group/> children specifying the natural-language name of a user-specified group, for the purpose of categorizing this contact into one or more roster groups.</p>
