    tid22 class="expanded"
      tid221 class="collapsed"
      tid222 class="collapsed"
    node titles filed under tid22, themed using theme('taxonomy_context_nodes')
    tid23 class="collapsed"
  tid3 class="collapsed"
  node titles filed under tid2, themed using theme('taxonomy_context_nodes')

The question is: is this correct ? and if not, what should it look like ? Note that this behaviour is themeable using theme_taxonomy_context_children_list
