A warning to appear in the MDN.
MDNWarning defines a warning to appear in the outgoing MDN. If any errors are found and not explicitly allowed in ErrorReportingFlags, the errors will take precedence and the warning will not be reported.
MDNWarning should be assigned when allowing errors to be ignored via the ErrorReportingFlags property. The MDN will indicate successful processing of the request, but will contain a warning field. The following warning is defined by the AS2 specifications:
"authentication-failed, processing continued"
Any other warnings are not defined by the specifications and may or may not be understood by the client.
This property is not available in the Sender.
