/**

 * find their parent, there is no mechanism for programmatically adding children to a Tag. This
 * is a problem for Metawidget, which needs to be able to build Tags, separately process them,
 * and <em>then</em> render them.
 * <p>
 * This method provides a way to defer the rendering of a child, to give us chance to process
 * it.
