<p>Each chunk of data is included as the XML character data of the &lt;data/&gt; element after being encoded as Base64 as specified in Section 4 of &rfc4648;. Each block MUST be a valid base64 block with padding at the end if needed.</p>
<p>The &lt;data/&gt; element MUST possess a 'seq' attribute; this is a 16-bit unsigned integer that acts as a counter for data chunks sent in a particular direction within this session. The 'seq' value starts at 0 (zero) for each sender and MUST be incremented for each packet sent by that entity. Thus, the second chunk sent has a 'seq' value of 1, the third chunk has a 'seq' value of 2, and so on. The counter loops at maximum, so that after value 65535 (2<span class='super'>15</span> - 1) the 'seq' MUST start again at 0.</p>

<p>The &lt;data/&gt; element MUST also possess a 'sid' attribute that ties the data chunk to this particular IBB session.</p>
<p>In the case of IQ stanzas, if the packet can be processed then the recipient MUST reply with an IQ stanza of type "result".</p>
