 new YAML

Hi Krzysztof,

> Although now I saw next patch, so clearly this commit is incomplete.

The split that Ryan has done here - by shifting to an identical separate
binding, then making the changes explicit - allows us to review the
actual changes without losing them in the move. Sounds like a benefit to
me?

That seems like a more complex approach. This is separate IP from the
2500 controllers, wouldn't that warrant a new binding spec?

Cheers,


Jeremy
