Hi,

yes I think the new changes improve the draft and make it easier to understand.

I wonder if there is a way in YANG to prevent the duplication of all
the fields between "interface" and "interface-state"... putting the
common fields into a section of their own and refer to them twice,
once as "read only" and once "read-writeable".
