  // - ${defaultValue} is the default value you set in your translation function.
  // - ${filePaths} will be expanded to an array that contains the absolute
  //   file paths where the translations originated in, in case e.g., you need
  //   to provide translators with context
  //
  // Any other custom property will be automatically extracted from the 2nd
  // argument of your `t()` function or tOptions in <Trans tOptions={...} />
  //
  // Example:
  // For `t('my-key', {maxLength: 150, defaultValue: 'Hello'})` in
  // /path/to/your/file.js,
  //
  // Using the following customValueTemplate:
  //
  // customValueTemplate: {
  //   message: "${defaultValue}",
  //   description: "${maxLength}",
  //   paths: "${filePaths}",
  // }
  //
  // Will result in the following item being extracted:

  //   "description": 150,
  //   "paths": ["/path/to/your/file.js"]

  resetDefaultValueLocale: null,
  // The locale to compare with default values to determine whether a default value has been changed.
  // If this is set and a default value differs from a translation in the specified locale, all entries
  // for that key across locales are reset to the default value, and existing translations are moved to
  // the `_old` file.
