/**
 * 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); Iterator it = d.getDetailEntries();
 * </PRE>
