This enumeration defines the different type of rates that can be provided by ExchangeRateProvider implementations. Hereby the rate provider's ProviderContext can contain additional information about the rates provided. Similarly, when accessing ExchangeRateProvider or CurrencyConversion instances corresponding attributes can be passed within an (optional) ConversionContext.
