- * 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>
