custom FXML builders in SceneBuilder

I think there are two usages of builders:
- construct compontents / controls programatically (ending in the build() call).
- mapping of FXML attributes to node properties, because in FXML everything must be a string.

For example, CalendarTextField has no builder class in the first sense (I used withers for that), but does have a class that converts the dateFormats (list of SimpleDateFormat strings) in an fxml file to an actual list of DateFormats instances.

If you can explain to me how to do this without a builder, but also without polluting CalendarTextField with FXML aspects, then I'll change the code.
