Table 7-68: Valid Property/Value Pairs for Join Datasets.
name	Value	Default	Description
data	none \| dataset name	None	The first source dataset.
data2	none \| dataset name	None	The second source dataset.
expr	String	data1-data2	When method is general: The way the evaluations in the first and second datasets is combined. data1 and data2 can be used as symbols for the values from the two datasets, respectively.
method	difference \| differencenorm \| explicit \| general \| product \| quotient \| sum	difference	How to combine the results from evaluating in the two source datasets.
solutions	all \| one	all	Whether to expose one or all solutions from the first dataset.
solutions2	all \| one	all	Whether to expose one or all solutions from the second dataset.
