    • <subscription> resource is a child resource of the "subscribed-to" resource.

  • The originator (resource subscriber) has RETRIEVE privileges to the "subscribed-to" resource in order to create the <subscription> resource.

  • Notification policies specified in the attributes can be applied to the <subscription>.
