Attribute Rule Constraint

Since version: 1.5

With the Attribute Rule Constraint profile, expressions can be written to evaluate whether or not a feature meets the criteria defined in the expression. This profile is used for constraint attribute rules in ArcGIS Pro. The script should return a Boolean with true indicating the feature meets the constraint criteria or false indicating it does not meet the criteria. You can also return a custom error message by returning a Dictionary of errorMessage.
