` field,
* or in three separate fields for day, month and year.
*
* # Configuration
*
* - 'showcalendar' (boolean): Determines if a calendar picker is shown.
* By default, "DHTML Calendar" is used,see http://www.dynarch.com/projects/calendar.
* CAUTION: Only works in NZ date format, see calendar-setup.js
* - 'dmyfields' (boolean): Show three input fields for day, month and year separately.
* CAUTION: Might not be useable in combination with 'showcalendar', depending on the used javascript library
* - 'dateformat' (string): Date format compatible with Zend_Date.
* Usually set to default format for {@link locale}
* through {@link Zend_Locale_Format::getDateFormat()}.
* - 'datavalueformat' (string): Internal ISO format string used by {@link dataValue()} to save the
* date to a database.
* - 'min' (string): Minimum allowed date value (in ISO format, or strtotime() compatible).
* Example: '2010-03-31', or '-7 days'
* - 'max' (string): Maximum allowed date value (in ISO format, or strtotime() compatible).
* Example: '2010-03-31', or '1 year'
*
* # Localization
*
* The field will get its default locale from {@link i18n::get_locale()}, and set the `dateformat`
* configuration accordingly. Changing the locale through {@link setLocale()} will not update the
* `dateformat` configuration automatically.
*
* # Usage
*
* ## Example: German dates with separate fields for day, month, year
*
* $f = new DateField('MyDate');
* $f->setLocale('de_DE');
* $f->setConfig('dmyfields');
*
* # Validation
*
* Caution: JavaScript validation is only supported for the 'en_NZ' locale at the moment,
* it will be disabled automatically for all other locales.
