Please notice there is currently NO WAY of having this JSON payload with the proper
DMNClient.
This is because the DMNClient currently forbids null-ifying the decision-name or
decision-id attribute.
Hence this is a case when not using the Kie Client but directly forging the JSON payload
manually (for instance from another/.NET/JS client)
