accessing swagger spec from proxy policy at runtime

[#1]

hi, Does anyone know if there is a way for policies in proxies to get information about the swagger operation that is being proxied please?

For example, if proxying: GET /myendpoint

And that operation within the swagger spec has a vendor extension of: x-myextension: xyz

Is there an easy way for a policy to access the x-myextension value at runtime?

Thanks
