The node name here should be just 'regulators', but that should be in
the MFD schema and you should remove this level here. So the MFD would
have:
properties:
regulators:
type: object

And this should be at the top level of this doc.

I prefer to see a single complete example in the MFD schema rather than
piecemeal schemas in each sub schema.
