Blocker Description
An issue with how embedded transformation configurations are included seems to have been introduced during 0.11.0.0. We are no longer seeing the `transforms.<xform>.type` being included in the validation output.

In this example, we should have seen `transforms.foo.type` and `transforms.bar.type` included as additional configs.
