source_ property
Source names the plane it is rolled up from, so a dimension that reads zero everywhere traces to a plane the organisation does not use rather than to a defect.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? source_;
