Provides a numeric value indicating the maximum number of recurrence instances that a calendar object resource stored in a calendar collection can generate.
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 [RFC2518]).
The CALDAV value that indicates the maximum number of recurrence instances that a calendar object resource stored in a calendar collection can generate. Any attempt to store a calendar object resource with a recurrence pattern that generates more instances than this value MUST result in an error, with the CALDAV:max-instances precondition (Section 18.104.22.168) being violated. In the absence of this property, the client can assume that the server has no limits on the number of recurrence instances it can handle or expand.
