pub.soap.handler:getFaultBlock

messageContext	Object Message context containing the SOAP message from which to retrieve the fault block. A message context contains properties for the SOAP message and provides access to the SOAP message. Integration Server creates the message context and passes it to the handler. All handlers invoked by a given instance of a SOAP request or SOAP response use the same message context, which enables you to use the message context to pass information among handlers.
documentTypes	String List Optional. Fully qualified name of the possible IS document types that could represent the structure of soapFault/detail. Specify document types that Integration Server created while creating the consumer or the WSDL first provider web service descriptor or ones that were created using the pub.soap.handler:generateDocumentTypesFromWSDL service. If you do not specify any document type, the service performs a literal conversion of the document; that is, the conversion will not consider style or use.
validate	String Optional. Flag that indicates whether you want the service to validate soapFault/detail against one of the IS document types specified in the documentTypes input parameter. Set validate to: true to validate the contents of soapFault/detail. To validate the service uses an IS document type from documentTypes that matches the structure. If none of the IS document types specified in documentTypes match, validation fails. If you do not use documentTypes to specify IS document types, the validation fails. If the validation fails, an exception is thrown. false to skip validating the contents of soapFault/detail. This is the default.
