+/**
+ * XMLRPC Server Faults
+ *
+ * Encapsulates an exception for use as an XMLRPC fault response. Valid
+ * exception classes that may be used for generating the fault code and fault
+ * string can be attached using {@link attachFaultException()}; all others use a
+ * generic '404 Unknown error' response.
+ *
+ * You may also attach fault observers, which would allow you to monitor
+ * particular fault cases; this is done via {@link attachObserver()}. Observers
+ * need only implement a static 'observe' method.
+ *
+ * To allow method chaining, you may use the {@link getInstance()} factory
+ * to instantiate a Zend_XmlRpc_Server_Fault.
