Hi Steve,
Your response seems to imply that the dfdl:calendarFirstDayOfWeek property is
only needed for "Week Date". However, I get an error:
[error] Schema Definition Error: Property calendarFirstDayOfWeek is not defined.
whenever I don't specify the property, even when I don't have a "Week Date".
<xs:element name="test2" type="xs:dateTime"
dfdl:calendarPatternKind="explicit"
dfdl:calendarCheckPolicy="strict"
dfdl:calendarPattern="MMMM dd',' yyyy 'at' hh:mm:ss"
dfdl:calendarFirstDayOfWeek="Monday"
dfdl:calendarDaysInFirstWeek="7"
dfdl:calendarTimeZone="UTC+6"
dfdl:calendarLanguage="en"/>
Thoughts?
/Roger

dfdl:calendarDaysInFirstWeek
I believe this is needed for the "Week Date" [1] calendar system. In this
system, you don't specify a day by year/month/day, but instead by year/week of
year/day of week. So today is 2019-27-1 (First day of the week, 27th week of
the year). So you need to know which day of the week is "first" in order to
know the correct day of the week. In the ISO week date the first day of a week
is Monday, but other system could use something different.
