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 error.
Context
The following products implement this profile:
- ArcGIS Pro

- ArcGIS Maps SDKs for Native Apps
Spatial reference
The spatial reference of the expression's data source1 determines the execution context's spatial reference.
Time zone
The time zone of the expression's data source1 determines the execution context's default time zone.
