request (as defined in Section 14.2 of [RFC4918]).

Description: This WebDAV property is present on a calendar collection
resource that has been shared by the owner, or on the calendar collection
resources of the sharees of the calendar. It provides a list of users to whom
the calendar has been shared, along with the "status" of the sharing invites
sent to each user. In addition, servers SHOULD include a CS:organizer XML
element on calendar collection resources of the sharees to provide clients
with a fast way to determine who the sharer is. A server's local privacy
policy may prevent sharees from knowing about other sharees on a shared
calendar. If that is so server will not include CS:user XML elements for
