      This table shows all the classes that implement the Element interface.
      For each class is shown:
      </p>
    <ul>
      <li>Its parent class</li>
      <li>Its public constructors</li>
      <li>Its methods starting with "add"</li>
    </ul>
    <p>
      These features are used to determine nesting and add...() behaviour in the pdf-builder DSL.
