[cisco-nas] Support for "percent" directive in per-session QoS

I believe this is possible reading the documentation at
http://www.cisco.com/en/US/products/ps6566/products_feature_guide09186a0080610dad.html

there is mention of it, but the question I want to ask is :

how does it know what the available bandwidth is such to be able to
calculate the percentage?

I mean, with a standard CBWFQ attached to an interface, it derrives this
from the interface bandwidth, but for vaccess QoS we are required to
nest the CBWFQ under a shaper, so does the percentage directive
use the shape average rate of this shaper?

Does anybody use this directive (interested for those whom use it for a
priority queue) and does it work?

Many thanks,
