Описание тега soapfault

The SOAP Fault element defines the following four subelements:

faultcode
The faultcode element is intended for use by software to provide an algorithmic mechanism for identifying the fault. The faultcode MUST be present in a SOAP Fault element and the faultcode value MUST be a qualified name.

faultstring
The faultstring element is intended to provide a human readable explanation of the fault and is not intended for algorithmic processing. The faultstring element is similar to the 'Reason-Phrase' defined by HTTP. It MUST be present in a SOAP Fault element and SHOULD provide at least some information explaining the nature of the fault.

faultactor
The faultactor element is intended to provide information about who caused the fault to happen within the message path. It is similar to the SOAP actor attribute but instead it indicates the source of the fault. The value of the faultactor attribute is a URI identifying the source.

detail
The detail element is intended for carrying application specific error information related to the Body element. It MUST be present if the contents of the Body element could not be successfully processed.
