/**
 * A container for <code>DetailEntry</code> objects. <code>DetailEntry</code>
 * objects give detailed error information that is application-specific and
 * related to the <code>SOAPBody</code> object that contains it.
 * <P>
 * A <code>Detail</code> object, which is part of a <code>SOAPFault</code>
 * object, can be retrieved using the method <code>SOAPFault.getDetail</code>.
 * The <code>Detail</code> interface provides two methods. One creates a new
 * <code>DetailEntry</code> object and also automatically adds it to
 * the <code>Detail</code> object. The second method gets a list of the
 * <code>DetailEntry</code> objects contained in a <code>Detail</code>
 * object.
 * <P>
 * The following code fragment, in which <i>sf</i> is a <code>SOAPFault</code>
 * object, gets its <code>Detail</code> object (<i>d</i>), adds a new
 * <code>DetailEntry</code> object to <i>d</i>, and then gets a list of all the
 * <code>DetailEntry</code> objects in <i>d</i>. The code also creates a
 * <code>Name</code> object to pass to the method <code>addDetailEntry</code>.
 * The variable <i>se</i>, used to create the <code>Name</code> object,
 * is a <code>SOAPEnvelope</code> object.
 * <PRE>
 *    Detail d = sf.getDetail();
 *    Name name = se.createName("GetLastTradePrice", "WOMBAT",
 *                                "http://www.wombat.org/trader");
 *    d.addDetailEntry(name);
