Yacine,

Handles are unique per Client-Type; i.e. one Client-Type "may" use the same
Handle as another Client-Type for the same Role Combination or whatever
Interface name specification is chosen.  In this case, the Handle can
identify the Interface and the Client-Type identifies the policy area.

Thank you for your explanations & sorry for having misunderstood the draft.
But I am still wondering about a point :
If there are as many client-types as policy areas, what is the handle
function in the provisioning model ?
I tought it was used this way (to specify areas) in a unique COPS-PR
session, but it's not the case since there is a COPS client type per
provisioning area.
