/**
 * This class represents SOAP1.1 Fault. This class will be used to marshall/unmarshall a soap fault using JAXB.
 * 

 * Example:
 * {@code
 *     
 *         soap:Client
 *         Invalid message format
 *         http://example.org/someactor
 *         
 *             
 *                 Test message
 *             
 *         
 *     
 * }
 * Above, m:msg, if a known fault (described in the WSDL), IOW, if m:msg is known by JAXBContext it should be unmarshalled into a
 * Java object otherwise it should be deserialized as {@link jakarta.xml.soap.Detail}
