/**
 * Drupal 6 taxonomy term source from database.
 *
 * Available configuration keys:
 * - bundle: (optional) The taxonomy vocabulary (vid) to filter terms retrieved
 *   from the source - can be an integer or an array. If omitted, all terms are
 *   retrieved.
 *
 * Examples:
 *
 * @code
 * source:
 *   plugin: d6_taxonomy_term
 *   bundle: 0
 * @endcode
 *
 * In this example terms of vocabulary with 'vid' equal to 0 are retrieved from
 * the source database.
 *
 * @code
 * source:
 *   plugin: d6_taxonomy_term
 *   bundle: [1, 3, 5]
 * @endcode
 *
 * In this example terms of vocabularies with 'vid' one of 1, 3, 5 are retrieved
 * from the source database.
 *
 * For additional configuration keys, refer to the parent classes.
 *
 * @see \Drupal\migrate\Plugin\migrate\source\SqlBase
 * @see \Drupal\migrate\Plugin\migrate\source\SourcePluginBase
 *
 * @todo Support term_relation, term_synonym table if possible.
