ASR1K QOS-configuring LLQ

Hi, in IOS-XE on ASR1K there are two ways how to configure LLQ, the first way like we know it from the ISR,7K2 and a new kind with using the priority level keyword (yes I know I can configure 2 priortity levels). As I understand correct using the priority level-key word there is no included policer like we have it with the priority ..kpbs keyword. so we have to define a sepereate policer to avoid that priority-traffic can consume all the available bandwidth.

Is there another difference in behaviour between the following two mehtods to configure it ?

!

class-map match-all realtime
match protocol rtp audio
!

class-map match-all signalling
match protocol sip
match protocol skinny
match protocol h323

!

policy-map test1

class realtime

  priority 1000

class signalling

  bandwidth 100

class class-default

  fair-queue

!

policy-map test2
class realtime
  priority level 1
  police cir 1000000
   conform-action transmit
   violate-action drop
class signalling
  bandwidth 100
class class-default
  fair-queue

Thx
