  * @param {number} [options.fadeDuration=300] Controls the duration of the fade-in/fade-out animation for label collisions, in milliseconds. This setting affects all symbol layers. This setting does not affect the duration of runtime styling transitions or raster tile cross-fading.
  * @param {boolean} [options.crossSourceCollisions=true] If `true`, symbols from multiple sources can collide with each other during collision detection. If `false`, collision detection is run separately for the symbols in each source.
  * @param {string} [options.accessToken=null] If specified, map will use this token instead of the one defined in mapboxgl.accessToken.
- * @param {string} [options.locale=null] A patch to apply to the default localization table for UI strings, e.g. control tooltips. The `locale` object maps namespaced UI string IDs to translated strings in the target language; see `src/ui/default_locale.js` for an example with all supported string IDs. The object may specify all UI strings (thereby adding support for a new translation) or only a subset of strings (thereby patching the default translation table).
