code: def make_back_author_contributions(self, body):

          contribution = self.article.root.xpath(cont_expr)

docs: Though this goes in the back of the document with the rest of the back
          matter, it is not an element found under <back>.
  
          I don't expect to see more than one of these. Compare this method to
          make_article_info_competing_interests()
