Hello,

I think it is also good to mention, that qos grop can also be set in 
following ways:

CAR:

 rate-limit input 2000000 1000000 1000000 conform-action transmit 
exceed-action set-qos-transmit 2

Policer:
policy-map test
  class class-default
     police 200000 100000 100000 conform-action transmit exceed-action 
set-qos-transmit 2

QOS-groups can be matched in:

CAR

rate-limit output qos-group 1 2000000 1000000 2000000 conform-action 
transmit exceed-action drop

Policy-map:

class-map match-all GOLD
  match qos-group 1
!
policy-map OUTPUT
  class GOLD
   bandwidth percent 50

(it's your example)

The only thing I would like to know if I can set QoS group in CAR and 
match in class-map.
