Error Events

The Transport Layer sends Error Events if an error occurred while processing the sending of the message. In other words, Error Events are NOT used for error messages or responses from the channel or data pool (that is, 1Sync).

The Error Events <MessageHeader> has the <RefOfMessageId> property which refers to a valid <MessageId> that caused the error to occur. The Error Event contains a <ErrorList> element following the <MessageHeader> tag in the SOAP <Header>.
