        public void setRejectUnsolicitedResponsesWithInResponseTo​(boolean rejectUnsolicitedResponsesWithInResponseTo)
        Controls if unsolicited Responses are rejected if they contain an InResponseTo value. If false using a validate method SamlResponse.isValid(String) with a null argument will accept messages with any (or none) InResponseTo value.
