Hi,

I was looking over this draft:

http://www.ietf.org/id/draft-schoenw-netconf-light-01.txt

I can agree with the problem statement:
There is a need for a constrained server which supports a limited subset of NETCONF operations.

I don't agree with the solution, since it is not backward-compatible with
any version of NETCONF.  A base:1.0 or base:1.1 peer will simply terminate
the session when a NETCONF Light peer does not advertise either of these capabilities.

YANG deviations can be used to fully describe the operations subset that a server implements,
and this is backward-compatible with the current version of NETCONF.
