title: How to add participants attributes fields with Limesurvey API?
body: <p>I would like to reproduce the whole survey creation process in Limesurvey with API.</p>
  
  <p>I try to add several attributes fields (like you do in the "Manage attributes" menu).</p>
  
  <p>I already tried to use <code>set_survey_properties</code> with the <code>attributedescriptions</code> element, but without success.</p>
  
  <p>Is it possible to do this with the API ?</p>
