+     * Defines the StringField object and sets its options.
+     * @param bool $required If `true`, this field is required to have a value at all times.
+     * @param bool $unique If `true`, this field must be unique from all other parent model objects. Enabling this
+     * option requires the Model $context to be set AND the Model $context must have a `config_path` set.
+     * @param mixed|null $default Assign a default string value to assign this Field if no value is present.
+     * @param array $choices An array of value choices this Field can be assigned. This can either be an indexed array
+     * of the exact choice values, or an associative array where the array key is the exact choice value and the array
+     * value is a verbose name for the choice. Verbose choice name are used by ModelForms when generating web pages
+     * for a given Model.
+     * @param string $choices_callable Assign a callable method from this Field object OR the parent Model context to
+     * execute to populate choices for this field. This callable must be a method assigned on this Field object OR the
+     * parent Model object that returns an array of valid choices in the same format as $choices. This is helpful when
+     * choices are dynamic and must be populated at runtime instead of pre-determined sets of values.
+     * @param string $datetime_format the PHP DateTime format this value should be formatted as.
+     * https://www.php.net/manual/en/datetime.format.php
+     * @param bool $allow_empty If `true`, empty strings will be allowed by this field.
+     * @param bool $allow_null If `true`, null values will be allowed by this field.
+     * @param bool $editable Set to `false` to prevent this field's value from being changed after its initial creation.
+     * @param bool $read_only If `true`, this field can only read its value and cannot write its value to config.
+     * @param bool $write_only Set the `true` to make this field write-only. This will prevent the field's current value
+     * from being displayed in the representation data. This is ideal for potentially sensitive fields like passwords,
+     * keys, and hashes.
+     * @param bool $representation_only Set to `true` to make this field only present in its representation form. This
+     * effectively prevents the Field from being converted to an internal value which is saved to the pfSense config.
+     * This should only be used for fields that do not relate directly to a configuration value.
+     * @param bool $many If `true`, the value must be an array of many strings.
+     * @param int $many_minimum When $many is set to `true`, this sets the minimum number of array entries required.
+     * @param int $many_maximum When $many is set to `true`, this sets the maximum number of array entries allowed.
+     * @param string|null $delimiter Assigns the string delimiter to use when writing array values to config.
+     *  Use `null` if this field is stored as an actual array in config. This is only available if $many is set to
+     *  `true`. Defaults to `,` to store as comma-separated string.
+     * @param string $verbose_name The detailed name for this Field. This name will be used in non-programmatic areas
+     * like web pages and help text. This Field will default to property name assigned to the parent Model with
+     * underscores converted to spaces.
+     * @param string $verbose_name_plural The plural form of $verbose_name. This defaults to $verbose_name with `s`
+     * suffixed or `es` suffixes to strings already ending with `s`.
+     * @param string $internal_name Assign a different field name to use when referring to the internal field as it's
+     * stored in the pfSense configuration.
+     * @param string $internal_namespace Sets the namespace this field belongs to internally. This can be used to nest
+     * the fields internal value under a specific namespace as an associative array. This only applies to the internal
+     * value, not the representation value.
+     * @param array $referenced_by An array that specifies other Models and Field's that reference this Field's parent
+     * Model using this Field's value. This will prevent the parent Model object from being deleted while it is actively
+     * referenced by another Model object. The array key must be the name of the Model class that references this Field,
+     * and the value must be a Field within that Model. The framework will automatically search for any existing Model
+     * objects that have the referenced Field assigned a value that matches this Field's value.
+     * @param array $conditions An array of conditions the field must meet to be included. This allows you to specify
+     * conditions of other fields within the parent Model context. For example, if the parent Model context has two
+     * fields, one field named `type` and the other being this field; and you only want this field to be included if
+     * `type` is equal to `type1`, you could assign ["type" => "type1"] to this parameter.
+     * @param array $validators An array of Validator objects to run against this field.
+     * @param string $help_text Set a description for this field. This description will be used in API documentation.
