window property
Window is the window class, one of 6h, day, week, month; anything else is refused rather than silently reclassified.
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? window;
