/**
 * Extension of {@link Locatable} for exceptions.
 * <p>
 * In order to dump location information in the stacktrace, the <code>getMessage()</code> method of
 * a {@link Locatable} exception should return a concatenation of the raw message (given in the
 * constructor) and the exception's location, e.g. "<code>foo failed (file.xml:12:3)</code>". However,
 * {@link Locatable}-aware classes will want to handle the raw message (i.e. "<code>foo failed</code>")
 * and location separately. This interface gives access to the raw message.
 * <p>
 * <strong>Note:</strong> care should be taken for locatable exceptions to use only immutable and
 * serializable implementations of {@link Location}
 * @see org.apache.cocoon.util.location.LocationImpl#get(Location)
 *
 * @since 2.1.8
 * @version $Id$
