Section 220.127.116.11 says:
Conformance: This property can be specified once in "VEVENT" or "VTODO" calendar component. ^^^^
It should say:
Conformance: This property can be specified in "VEVENT" or "VTODO" calendar component.
The word "once" was mistakenly introduced in RFC 5545.
RFC 2445 didn't have this issue.
