+        In some cases it is useful to associate some options with an
+        address pool from which a client is assigned a lease. Pool
+        specific option values override subnet specific and global
+        option values. If the client is assigned multiple leases from
+        different pools, the server will assign options from all pools
+        from which the leases have been obtained. However, if the
+        particular option is specified in multiple pools from which
+        the client obtains the leases, only one instance of this
+        option will be handed out to the client. The server's
+        administrator must not try to prioritize assignment of pool
+        specific options by trying to order pools declarations in the
+        server configuration. Future Kea releases may change the order
+        in which options are assigned from the pools without any
+        notice.
