Type

Property

Protected

MUST

Returned by allprop

SHOULD NOT

Valid for resource types

urn:ietf:params:xml:ns:caldav:calendar

###Purpose

Provides a numeric value indicating the maximum number of ATTENDEE properties in any instance of a calendar object resource stored in a calendar collection.

###Value A numeric value (integer greater than zero)

###Conformance

This property MAY be defined on any calendar collection. If defined, it MUST be protected and SHOULD NOT be returned by a PROPFIND DAV::allprop request (as defined in Section 12.14.1 of RFC 2518).

###Description

The CALDAV:max-attendees-per-instance is used to specify a numeric value that indicates the maximum number of iCalendar ATTENDEE properties on any one instance of a calendar object resource stored in a calendar collection. Any attempt to store a calendar object resource with more ATTENDEE properties per instance than this value MUST result in an error, with the CALDAV:max-attendees-per-instance precondition (Section 5.3.2.1) being violated. In the absence of this property, the client can assume that the server can handle any number of ATTENDEE properties in a calendar component.
