This is going to be painful to represent due to how the push API allows
mixed types (strings or objects) and mixed top-level keys ("content" rule kind
allowing "pattern" as a top-level key). We may wish to re-visit the design
of this API for v2.
The tool used for validating swagger 2.0 schemata does not currently
support deep-nested definitions from other files. Until it does, keep
the definitions in a separate file each in a definitions folder. This
will be replaced with a definitions.yaml in the future.
