 <section1 topic='Application Format' anchor='format'>
   <p>A Jingle RTP session is described by a content type that contains one application format and one transport method. Each &lt;content/&gt; element defines a single RTP session. A Jingle negotiation MAY result in the establishment of multiple RTP sessions (e.g., one for audio and one for video). An application SHOULD consider all of the RTP sessions that are established via the same Jingle negotiation to be synchronized for purposes of streaming, playback, recording, etc.</p>
-  <p>The application format consists of one or more encodings contained within a wrapper &lt;description/&gt; element qualified by the 'urn:xmpp:jingle:apps:rtp:0' namespace &VNOTE;. In the language of <cite>RFC 4566</cite> each encoding is a payload-type; therefore, each &lt;payload-type/&gt; element specifies an encoding that can be used for the RTP stream, as illustrated in the following example.</p>
