ElementConstraints:
Signature: reducer_inputs_output() : Boolean;
Description: The reducer behavior must have two input parameters and one output parameter,
of types compatible with the types of elements of the input collection.
Expression: true
Signature: output_types_are_compatible() : Boolean;
Description: The type of the output must be compatible with the type of the output of
the reducer behavior.
Expression: true
Signature: input_type_is_collection() : Boolean;
Description: The type of the input must be a collection.
Expression: true
