I think there is no need to limit the scope of configuration management
to the 6 specific types of configuration data listed below.  This WG
should not develop configuration commands for any specific technology 
such as logical interfaces or port diagnostics.  

It is important that the protocol be capable of manipulating 
configuration for any network service, not some arbitrary subset.
I don't believe the transaction requirements will differ
significantly based on the content of the data model.  Your list
seems to focus on enable and disable commands, as if on/off
switches would be sufficient for configuration.  Maybe this
isn't what you meant.

I think these are the proper goals for the NM Roadmap slide.
That doesn't mean that this WG will achieve all of these goals
with its initial charter. It just means we can start moving in
the right direction.

You have mostly restated the original charter text. I'm not sure
it makes the goals more understandable, though.
