Symfony3 documentation seems to suggest Nelmio 3 is able to parse FOSRest annotation, and to generate a Swagger JSON file accordingly.
This tutorial, in French unfortunately, says that it uses @Rest\QueryParam and that Nelmio is able to export it using as a Swagger file.
I will give it a try this weekend. If this does not work, we know that Nelmio can read FOSRest annotations and generate the right HTML doc from it. So I guess the best would be to make a PR to Nelmio project to allow this behavior.
