+/// This file defines common elements used for client classification.
+/// It is simple for now, but the complexity involved in client
+/// classification is expected to grow significantly.
+///
+/// @todo This file should be moved to dhcpsrv eventually as the classification
+/// is server side concept. That is not possible yet, as the Pkt4 and Pkt6
+/// classes have server-side implementation, even though they reside in the
+/// dhcp directory.
