If no Table Entry ID is specified in the GET, a listing of all Raw Message Rules will be returned along with their associated Table Entry IDs. A Message Table may contain Header Rules, Request Line Rules, Status Line Rules, and Raw Message Rules: all will need to be queried to determine the message table membership. These table entry identifiers can be used to collect resource schema element values via the GET spmmessagetable id - spmheaderrule id method.
