The SAX2 solution:

  interface MagicDataHandler
    public void date (Date date) throws SAXException;
    public void currency (Currency currency) throws SAXException;
    public void integer (int integer) throws SAXException;


  SAXReader r = new MagicDataReader();
  MagicDataHandler h = new MyMagicDataHandler();
  try {
    r.setProperty("http://www.foo.com/props/magic-data-handler", h);
  } catch (SAXException e) {
    System.err.println("Reader does not support a MagicDataHandler");

Presumably, in place of characters() events, your client application
would receive date, currency, and integer events.  This would be an
especially nice application for SAX2 filters, once we have a stable
and generally-accepted data-typing mechanism (no, guys, notations may
be stable but they're not yet generally-accepted).

Let me know if it looks like we've done this one right.

All the best,
