Hi Steve, Would it be accurate to say:
- Always specify dfdl:calendarFirstDayOfWeek and dfdl:calendarDaysInFirstWeek in any element declaration that uses dfdl:calendarPattern - It doesn't matter what value you assign to the dfdl:calendarFirstDayOfWeek and dfdl:calendarDaysInFirstWeek properties. True? /Roger -----Original Message----- From: Steve Lawrence <[email protected]> Sent: Monday, July 1, 2019 9:41 AM To: [email protected] Subject: Re: I don't understand dfdl:calendarFirstDayOfWeek and dfdl:calendarDaysInFirstWeek Technically the property might only be needed if there's a week date pattern in textCalendarPattern, but Daffodil doesn't try to be that smart. If representation is text and the type is date/time, we're going to require all the calendar properties. The calendarDaysInFirstWeek property is also similar. I believe that is also only need to week dates, but again, we're always going to require it.
