    Figure 1: Shows the assumed communication  model for both a layer 7
       location configuration protocol and a dereference  protocol:

   (the following paragraph should be #2 below this Figure in the doc)

   For completeness, Figure 1, includes the interaction between the 
   owner of the Target and the LIS to establish rulemaker policies.  
   This is communications path (1b).  This interaction needs to be 
   done before the LIS will authorize anything of than default policies
   to a dereference request for location of the Target.
