   * The basic operation of this Pipe is that it replaces wi:widget tags (having an id attribute)
   * by the XML representation of the corresponding widget instance.
   *
   * <p>These XML fragments (normally all in the {@link Constants#WI_NS "Woody Instance"} namespace, can
   * then be translated to a HTML presentation by an XSL. This XSL will then only have to style
   * individual widget, and will not need to do the whole page layout.
   *
   * <p>The content of the &lt;widget&gt; element will be re-inserted in the XML generated by the Widget
   * (as a child of its root element, before the closing tag), and wrapped inside a &lt;wi:styling&gt;
   * element. This allows to pass extra information to the XSLT that will render the widgets. For example,
   * this could be used to define the textbox width or the listbox style (dropdown or normal), ...</p>
   *
   * <p>Additionally, this transformer supports the following tags:
   * <ul>
   *  <li><strong>widget-label</strong>: used to insert the label of a widget. Requires an "id" attribute.
   *  <li><strong>repeater-widget</strong>: provides special treatement for repeater widgets. The content
   *   of the repeater-widget element will be used as a template to generate each of the rows of the repeater.
   *  The repeater-widget element requires an "id" attribute.
   *  <li><strong>repeater-widget-label</strong>: inserts the label of a widget contained by the repeater.
   *  Requires an "id" attribute (identifying the repeater) and a "widget-id" attribute (identifying the widget
   *  in the repeater).
   *  <li><strong>repeater-size</strong>: inserts an element &lt;repeater-size id="" size=""/> containing the
   *   size (number of rows) in the repeater.
   * </ul>
   *
   * <p>Woody ships with an XSL that can style all the widgets that are provided by the core Woody framework.
