import org.xml.sax.SAXException;


public interface DeclHandler {

  public abstract void elementDecl(String name, String model)
   throws SAXException;

  public abstract void attributeDecl(String elementName, String attributeName, 
   String type, String defaultValue, String value) throws SAXException;

  public abstract void internalEntityDecl(String name, String value)
   throws SAXException;

  public abstract void externalEntityDecl(String name, String publicId,
