To my understanding, a root class that has a higher ceil than rate 
can always use bandwidth up to it's ceil. Thus it would be more 
correct to set the rate to 100% here (whatever that is) as well.

If class 1:19 is the only child of class 1:11, it can always use 
whatever bandwidth the parent class can get. So the parent class 
does not have any limiting factor here and you can just skip it 
and attach 1:19 to 1:10 directly.

The only difference to the tree before is that you grouped all non-voip 
traffic under a separate parent class which is capped at 80%, so voip 
always has 20% of available bandwidth which can not be taken away from 
it, right? If that was your intention, then it's fine.
