Provides a numeric value indicating the maximum size of a resource in octets that the server is willing to accept when a calendar object resource is stored in a calendar collection.
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 numeric value that represents the maximum size in octets that the server is willing to accept when a calendar object resource is stored in a calendar collection. Any attempt to store a calendar object resource exceeding this size MUST result in an error, with the CALDAV:max-resource-size precondition (Section 18.104.22.168) being violated. In the absence of this property, the client can assume that the server will allow storing a resource of any reasonable size.
