Description
To represent the result of an evaluation that is null, parameters could be either left out of the Parameters response, or provided with some indicator. Some implementations currently provide the result as a string representation (such as 'null' or '{}'), but this is technically incorrect. A better solution would be to use the dataAbsentReason extension for this purpose.
