/**
 * XmlRpc Request object
 *
 * Encapsulates an XmlRpc request, holding the method call and all parameters.
 * Provides accessors for these, as well as the ability to load from XML and to
 * create the XML request string.
 *
 * Additionally, if errors occur setting the method or parsing XML, a fault is
 * generated and stored in {@link $_fault}; developers may check for it using
 * {@link isFault()} and {@link getFault()}.
