Content Element Detail (all declarations; defined in this component only; 1/1)
return-argument
Type:
anonymous, empty content
A list of expressions, each of which is evaluated and equates to an element in the result message. If just one 'return-argument' is configured, the result will be the evaluation of that expression rather than an object array.
