ME3400 Limit Bandwidth Via VLAN

I'm having issues trying to get VLAN Bandwidth Limiting to apply only to one particular VLAN.  I can get the rate limiting to work on the customer port along with the service provider port, but on the service provider port the rules seem to apply to all VLANS not just the one in particular.  When pushing traffic across the VLAN201 in this example, the downstream traffic is limited to 5Mb but should be applied to that VLAN.  This is making me scratch my head as to why the rule is applying across all VLANS and not just the 1112 in this example:

class-map match-any vlan_1112
  match vlan  1112
policy-map LIMIT
 class class-default
    police cir 5000000
      conform-action transmit
      exceed-action drop
policy-map UPLINK-LIMIT
 class vlan_1112
   service-policy LIMIT

interface GigabitEthernet0/11
 switchport access vlan 201
 media-type rj45
 speed 100
interface GigabitEthernet0/12
 switchport access vlan 1112
 service-policy input LIMIT
interface GigabitEthernet0/13
 description Switchport Trunk to ASR9K
 port-type nni
 switchport trunk allowed vlan 100,1112
 switchport mode trunk
 service-policy input UPLINK-LIMIT

Try changing from "input" policies to "output" policies.

When attempting that I received the following errors:

QoS: Configuration failed. Police can not be configured in class-default, policy LIMIT

QoS: Configuration failed. Only class-default is allowed in top level of an output policy
