[Ietf-calsify] Issue 13: confusion in DTSTART text about "if specified" and BY rules

[Bernard Desruisseaux]

[ This issue was brought up by Reinhold on the ietf-calendar mailing list. ]

In section 4.3.10 Recurrence Rule of RFC 2445 it says:

 > The COUNT rule part defines the number of occurrences at which to
 > range-bound the recurrence. The "DTSTART" property value, if
 > specified, counts as the first occurrence.

I would like to remove "if specified" given that DTSTART should be
REQUIRED when either RRULE or EXRULE are present.

NEW TEXT:

 > The COUNT rule part defines the number of occurrences at which to
 > range-bound the recurrence. The "DTSTART" property value counts as
 > the first occurrence.

Cheers,
Bernard
