Here's another attempt at the SAX2 DTDDeclHandler, adding element type
declarations (the handlerID is http://xml.org/sax/handlers/dtd-decl):

// DTDDeclHandler.java -- receive extended DTD declarations
// $Id: DTDDeclHandler.java,v 1.1 1999/03/26 14:58:47 david Exp david $

package org.xml.sax;

public interface DTDDeclHandler extends SAX2Handler
    public final static int MODEL_ELEMENTS = 1;
    public final static int MODEL_MIXED = 2;
    public final static int MODEL_ANY = 3;
    public final static int MODEL_EMPTY = 4;

    public final static int ATTRIBUTE_DEFAULTED = 1;
    public final static int ATTRIBUTE_IMPLIED = 2;
    public final static int ATTRIBUTE_REQUIRED = 3;
    public final static int ATTRIBUTE_FIXED = 4;

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

    public abstract void attributeDecl (String element,
					String name,
					String type,
					String defaultValue,
					int defaultType,
					EntityRefList entityRefs)
	throws SAXException;

    public abstract void externalEntityDecl (String name,
					     boolean isParameterEntity,
					     String publicId,
					     String systemId)
	throws SAXException;

    public abstract void internalEntityDecl (String name,
					     boolean isParameterEntity,
					     String replacementText)
	throws SAXException;

// end of DTDDeclHandler.java

To this take, I've added the elementDecl() callback.

All the best,
