[Nml-wg] Possibility of changes (was Re: Interface vs Port)

[Jason Zurawski]

Hi Jeroen/All;

The rest of this conversations seems to have disappeared, are we done 
discussing the purpose of this thread?  Will we need yet another subject 
change?

This is an opportunity to show the work being produced by the NML working group as an interoperable and legitimate way to describe network topology.  Using something different, with no real ties to the working group, means that what is being produced really is "demo" code that will need to be 'changed' when the final standard is produced.  This seems like a bit mistake, and a loss for the WG in my opinion.

If you believe this to be the right way forward, I suppose there is not 
a lot that can be done to change things at this point.  This still does 
not sound like the best idea to me, because I have a little experience 
in the area of ideas being 'impacted' into code.  Taking "no action" is 
a stronger force than taking action, and it seems to me that once there 
is a working implementation using this fake/minimal topology, there will 
not be a lot of momentum to change things that are in place and working.

My $0.02 (or 0.013 Euro).

Thanks;
