Maybe so Michael:

We might simplify by omitting:

"
In detail, the WG will consider operations:
(1) from  the device routing layer to the PCE for
	(i) sending topological information and routing metrics, and 
	(ii) getting on-demand routing information; and 
(2) from the device 6top sublayer to the PCE for 
	(a) exporting neighboring and link quality statistics and 
	(b) requesting to (re)compute and install a track that meets explicit flow requirements.
"
>From the charter though we all know that this work has to be done. 

The reason why it's there now is that while doing our homework we found that PCEP only covers a subset of that list.
At some point we will have to map individually all those steps and the standardization work that covers it all may take more than one RFC...

Cheers,

Pascal

It seems like you are trying to engineer the solution in the charter text.
