-- Returns the name, Amazon Resource Name (ARN), rules, definition, and
-- effective dates of a Cost Category that\'s defined in the account.
--
-- You have the option to use @EffectiveOn@ to return a Cost Category
-- that\'s active on a specific date. If there\'s no @EffectiveOn@
-- specified, you see a Cost Category that\'s effective on the current
-- date. If Cost Category is still effective, @EffectiveEnd@ is omitted in
-- the response.
