The first mandatory <list> attribute is "uri," which contains the uri that corresponds to the list. The second mandatory <list> attribute is "version," which contains a number from 0 to 232 1. The third mandatory attribute is "fullState." The "full-State" attribute indicates whether the NOTIFY mes- sage contains information for every resource in the list. Finally, <list> ele- ments may contain a "cid" attribute. If present, the "cid" attribute identifies a section within the multipart/related body that contains aggregate state information for the resources contained in the list. <list> <resource> <name> <instance> <resource> <resource> The resource list contains one <resource> element for each resource being reported in the notification. These resource elements contain attributes that identify meta-data associated with each resource. The "uri" attribute identifies the resource to which the <resource> element corresponds. Each list and resource element contains zero or more name elements. These name elements contain human readable descriptions or names for the resource list or resource. Each resource element contains zero or more instance elements. These instance elements are used to represent a single notifier for the resource. The "id" attribute contains an opaque string used to uniquely identify the instance of the resource. The "state" attribute contains the subscription state for the identified instance of the resource. This attribute contains one of the values "active," "pending," or "terminated." Finally, the "cid" attribute, which is present if the "state" attribute is "active," identifies the section within the multipart/related body that contains the actual resource state.
