One final thought on this I-D.  As most of you will have seen,
I have queried the placement of the network type wson-topology
under te-topology instead of under network-types not seeing
an explanation of the rationale of the tree structure in the RFC that 
set up the namespace for this scenario.  I struggle to see the benefit 
of one over the other when it comes to using the YANG modules in a 
network, creating the data and accessing it, and have a vague concern 
that this hierarchy may turn out to be limiting in future.
However, noone else agrees with me so I will leave it at that; I post
this here for completeness, the discussion having spanned three WG.
I note that the other CCAMP modules use the same placement.
