/**
* {@code JFormattedTextField} supporting the {@code Referenznummer10} type.
* This textfield uses the {@link Referenznummer10} type for parsing and formatting. An empty string value is treated
* as {@code null}. Property {@code format} controls formatting and takes one of the format constants defined in class
* {@code Referenznummer10}. By default the {@code ELECTRONIC_FORMAT} is used. The {@code validating} flag controls
* validation of values entered into the textfield. If {@code true} (default), a {@code DocumentFilter} is registered
* with the textfield disallowing invalid values, that is, values which are not {@code null} and not empty strings and
* for which the {@link Referenznummer10#parse(String)} method throws a {@code ParseException}.
