      public class XMLDTDLoader
      extends XMLDTDProcessor
      implements org.apache.xerces.xni.grammars.XMLGrammarLoader

  The DTD loader. The loader knows how to build grammars from XMLInputSources. It extends the DTD processor in order to do this; it's a separate class because DTD processors don't need to know how to talk to the outside world in their role as instance-document helpers.

  This component requires the following features and properties. It know ho to set them if no one else does:from the
