Conflict between Swagger 2.0 and OpenAPI 3.0.0

[vinay0410]

Hi,
I used flex recently to validate request and response of an API, and would like to mention that it's a great tool, and have features which lots of other tools out there don't have, and the documentation depicts them greatly 😃 .

But I ran into a problem, using this with swagger 2.0 . It says that type: file isn't supported. I looked more into it and realised that OpenAPI 3.0.0 doesn't support file and therefore changed it to string.

Also, it supports anyOf and oneOf, which came in OpenAPI 3.0.0 . So , I concluded that it supports OpenAPI 3.0.0 , although the README.md says something else.

Therefore I converted my swagger 2.0 documentation to openapi 3.0 using swagger-editor, but it failed for that too.

So, could any one please shed some light on the fact, that which version, and set of features, does this repository currently supports.
