<p>The server MUST return the changed collections in the chronological order that they were changed (most recent last). If a collection has been modified, created, or removed <em>after</em> the time specified by the 'start' attribute, then the server MUST include it in the returned result set page of collections (unless the specified maximum page size would be exceeded). Each &lt;changed/&gt; or &lt;removed/&gt; collection element (for modified/created, or removed collections respectively) in the returned list MUST include the 'with' and 'start' attribues (and MAY include the 'exactmatch' attribute if that was specified in the request). The XML character data of the &lt;last/&gt; element is a unique, persistent identifier created by the server, which MUST be treated as opaque by the client.</p>

<p>Note: Along with its copy of the archive the client SHOULD save the most recent &lt;last/&gt; identifier that it received from the server.
