After some further testing I see now this behaviour:

- NPE-G2 with 12.2(33)SRE2
- receiving L2TP/VPDN PPP sessions via GE interface
  (LNS is a stub router)

Test 1 (police)
===============
!
policy-map PM-STCR-ADSL-3M
  class class-default
    police 3000000
!

Result:

1) I can apply this PM to an Session/VirtAccInt through RADIUS via
    "lcp:interface-config=service-policy..."
     or
    "ip:sub-policy-Out..."

2) I can *not* apply this PM to an Session/VirtAccInt through RADIUS via
    "ip:sub-qos-policy-out..."


Test 2 (shape)
==============
!
policy-map PM-STCR-ADSL-3M
  class class-default
    shape average 3000000
!

Result:

1) I can *not* apply this PM to an Session/VirtAccInt through RADIUS via
   any of this 3 attribute values:
    "lcp:interface-config=service-policy..."
    "ip:sub-policy-Out..."
    "ip:sub-qos-policy-out..."


So I can use only 'police' but not 'shape', 'priority' or 'bandwidth' in
the policy-maps. If I use shape/priority/bandwidth in any parent or
child policy-map, the whole policy will not be applied to the
Virtual-Access interface.

Is there any other thing that I may have overlooked?
