/**
 * 
 * An enumeration class that describes the different validation phases.
 * 
 * An instance of this class is passed to the
 * {@link FieldHandler#validate(ValidationPhase)} method. This
 * method can then determine, which validation to perform.
 * 
 * 
 * The form framework distinguishes between validation on the field and the form
 * layer. The field layer deals with syntactic checks. Here the user input is
 * verified to match the expected data type, e.g. is the text entered by the
 * user a valid number or a valid date? The form layer is more about semantic.
 * After the user's input has been transformed into the target data types
 * constraints for the single fields are checked, e.g. is the number between 0
 * and 100 or is the date in the future.
