/**
 * <p> "Entity" implementation.  This is a non-core DOM class, supporting the
 * "XML" feature.  There are two types of entities, neither of which works
 * particularly well in this API:</p><dl>
 *
 * <dt><em>Unparsed Entities</em></dt>
 *      <dd>Since ENTITY/ENTITIES attributes, the only legal use of unparsed
 *      entities in XML, can't be detected with DOM, there isn't much point in
 *      trying to use unparsed entities in DOM applications.  (XML Linking is
 *      working to provide a better version of this functionality.) </dd>
 *
 * <dt><em>Parsed Entities</em></dt>
 *      <dd> While the DOM specification permits nodes for parsed entities
 *      to have a readonly set of children, this is not required and there
 *      is no portable way to provide such children.  <em>This implementation
 *      currently does not permit children to be added to Entities.</em>
 *      There are related issues with the use of EntityReference nodes.  </dd>
 *
 * </dl>
 *
 * <p> In short, <em>avoid using this DOM functionality</em>.
