"cashRounding" attributes when formatting currency values.

+ Implementations using the locale data provided by the Common Locale Data Repository (available at <a href="https://cldr.unicode.org/">https://cldr.unicode.org/</a>) should determine the number of minor units displayed using the value of the *"digits"* attribute rather than the value of the*"cashDigits"* attribute. Implementations using CLDR should ignore the *"rounding"* and *"cashRounding"* attributes, since CLDR's values for these attributes do not take into account jurisdictional differences in required rounding increments for currency values.
