Description

This parameter can be specified on properties with a CAL-ADDRESS value type. The parameter identifies the participation status for the calendar user specified by the property value. The parameter values differ depending on whether they are associated with a group-scheduled "VEVENT", "VTODO", or "VJOURNAL". The values MUST match one of the values allowed for the given calendar component. If not specified on a property that allows this parameter, the default value is NEEDS-ACTION. Applications MUST treat x-name and iana-token values they don't recognize the same way as they would the NEEDS-ACTION value.
