/**
 * Drupal 6 field instances source from database.
 *
 * Available configuration keys:
 * - node_type: (optional) The content type (machine name) to filter field
 *   instances retrieved from the source. If omitted, all field instances are
 *   retrieved.
 *
 * Example:
 *
 * @code
 * source:
 *   plugin: d6_field_instance
 *   node_type: page
 * @endcode
 *
 * In this example field instances of type page are retrieved from the source
 * database.
 *
 * For additional configuration keys, refer to the parent classes.
 *
 * @see \Drupal\migrate\Plugin\migrate\source\SqlBase
