* This is the DTD-only parser configuration. It extends the basic
* configuration with a standard set of parser components appropriate
* to DTD-centric validation. Since
* the Xerces2 reference implementation document and DTD scanner
* implementations are capable of acting as pull parsers, this
* configuration implements the
* <code>XMLPullParserConfiguration interface.
* <p>
* In addition to the features and properties recognized by the base
* parser configuration, this class recognizes these additional
* features and properties:
* <ul>
* <li>Features
