MLR
A Messaging Level Response message can be used in the choreography of the exchange of a business
document to improve reliability by allowing a receiver of a business document to inform the sender about the
results of receivers validations and, in case of negative results, to inform the sender about the nature of the
errors as well as their details. They may allow the sender of the document to take appropriate action.
