| /** |
| * The DTD validator. The validator implements a document |
| * filter: receiving document events from the scanner; validating |
| * the content and structure; augmenting the InfoSet, if applicable; |
| * and notifying the parser of the information resulting from the |
| * validation process. |
| * <p> Formerly, this component also handled DTD events and grammar construction. |
| * To facilitate the development of a meaningful DTD grammar caching/preparsing |
| * framework, this functionality has been moved into the XMLDTDLoader |
| * class. Therefore, this class no longer implements the DTDFilter |
| * or DTDContentModelFilter interfaces. |
| * <p> |
| * This component requires the following features and properties from the |
| * component manager that uses it: |
| * <ul> |
| * <li>http://xml.org/sax/features/namespaces</li> |
| * <li>http://xml.org/sax/features/validation</li> |
