Validation of the generated Swagger 2 file via tools like the swagger editor or swagger-cli reveals that there are schema violations in the file.

Violations

host String does not match the pattern of "^[{}/ :\\](?::\d)?$"

host: n/a

Property example is not allowed

parameters:   - name: physical-location-id

     description: Unique identifier for physical location, e.g., CLLI
     required: true
     type: string
     example: __PHYSICAL-LOCATION-ID__

Property also requires is not allowed

properties:   model-invariant-id:     type: string
    description: the ASDC model id for this resource or service model.

Other issues

• A license header is put into the description even though there already is a dedicated license field
• There is a contact block that only contains n/a values
• the description of the default response is referencing to an (internal?) AT&T wiki page that can't be reached
• When there's no description available for a parameter, a default description of n/a is added. The description key is not mandatory and it adds no value to add a meaningless placeholder for it
