   How is it possible to restrain the tag cloud to tags from only one category? On Amaury's site, I saw the code for the opposite, i.e. the code to display all tags EXCEPT the ones from a given category:

   <?php

   // ID de la catégorie
   $category_id = 3;

   // On récupérer les ID des articles
   $post_ids = get_objects_in_term( $category_id, 'category' );

   // On récupérer les ID des tags liés à ces articles
   $tag_ids = wp_get_object_terms( (array) $post_ids, 'post_tag', array('fields' => 'ids') );

   // On passe le tableau des tags dans une chaine de caractère séparé de ","
   $tag_param = '';
   if ( ! empty($tag_ids) ) {
   $tag_param = 'exclude=' . implode(',', (array) $tag_ids );
   }

   // On utilise Simple Tags - Nuage de tags
   st_tag_cloud('number=100&'.$tag_param);

   ?>

   Now, how to do the opposite? I tried replacing the "exclude=" by "include=", but to no avail (all tags from all categories get displayed).
