It seems like the System.DateOnly constructors should provide for some exceptions. What if someone enters a year outside the range 1-9999? What if they enter Feb 29 with a year that is not a leap year? What if they enter Feb 30 or Apr 31?

2023-11-13T18:26:01.7766667+00:00 I don't see the exceptions mentioned in the online documentation for DateOnly. For instance, here is the only information provided for the constructor DateOnly(Int32, Int32, Int32).
DateOnly(Int32, Int32, Int32)
Creates a new instance of the DateOnly structure to the specified year, month, and day.
public DateOnly (int year, int month, int day);
Parameters
year Int32
The year (1 through 9999).
month Int32
The month (1 through 12).
day Int32
The day (1 through the number of days in month).

2023-11-13T19:06:49.6+00:00 OK, I did report it via feedback, but notice that even the .NET 7 (complete) version of the documentation did not provide exception information. Thanks for putting up with me in this question.
