Survey of RRULE/COUNT behavior, was Re: [Ietf-calsify] RRULE's and COUNT

[Bernard Desruisseaux]

I propose a different survey.

1- Import the attached iCalendar object.

2- Report the dates of the recurrence instances generated by
    your calendar application:

    a) Monday,  October 16, 2006
       Tuesday, October 17, 2006
       Tuesday, October 24, 2006

    b) Monday,  October 16, 2006
       Tuesday, October 17, 2006
       Tuesday, October 24, 2006
       Tuesday, October 31, 2006

    c) Tuesday, October 17, 2006
       Tuesday, October 24, 2006
       Tuesday, October 31, 2006

Thanks,
Bernard
