Does OpenAPI 3.0 supports enum as reusable component for Path Parameters?

Hi ssingh137 ,

Yes it's possible to reuse schemas in Parameters.

See an example here: https://app.swaggerhub.com/apis/SwaggerPMTests/reuseable-enum/1.0.0#/default/get_foo__bar_

For more info around Path Parameters, see: https://swagger.io/docs/specification/describing-parameters/#path-parameters

Note: You cannot have sibling fields next to a $ref. In your example you have `type: string` next to a `$ref: ...` and that is invalid.
