Re: [Rtg-yang-coord] Clearing all stats in a container

Hi,

it was generally found useful when we did the interfaces and ip YANG
models to properly separate config data from state data. And this is
not just counters, it could include other things where operational
state can be different from the configured state.

One reason to keep them in a container of their own is to be able to perform bulk operations on them. Of course, as Juergen pointed out, clearing stats may not be one of them. But if you wanted to say <get> all the stats on a particular module, you would do a <get> on the container i.e. statistics in this example, and you would have all the stats.
