     <div class="box"><p>General remarks:</p>
     <ul>
       <li><p>The algorithm strongly distinguishes between character data (sequences of Unicode code points) and octet strings (sequences of 8-bit bytes). Whenever character data is encoded to octet strings in the following algorithm, the UTF-8 as specified in &rfc3629; encoding is used. Whenever octet strings are sorted in the following algorithm, the i;octet collation as specified in &rfc4790; is used.</p></li>
-      <li><p>The algorithm uses the <tt>xml:lang</tt> attribute. Implementations must take implicit values for the <tt>xml:lang</tt> attribute into account, for example those inherited from the disco#info or the IQ element.</p></li>
