QoS in Frame Relay (MQC vs Legacy)

One quick question. What is the difference between

1. service policy being applied to a frame-relay sub-interface

int se 0/0.1 point-to-point
service policy <x>

2. frame-relay map-class being applied to the DLCI in the same sub-interface

int se 0/0.1 point-to-point
frame-relay interface-dlci 1
class <y>

Can someone throw some light on the above two scenarios ?
