It is not possible to access swagger content from the mediation script using $ref due to,

1. x-mediation-script is in JS and could not use swagger syntax in code.
2. API Manager does not process the script. Therefore, when publishing the API, only the x-mediation-script content is copied to the synapse file.

As the solution, create a JS variable in the x-mediation-script and use it.

    mc.setProperty('CONTENT_TYPE', 'application/json'); // Set the content type of the payload to the message context
    var town = mc.getProperty('uri.var.town');          // Get the path parameter 'town' and store in a variable
    mc.setPayloadJSON('{ "Town" : "'+town+'"}');        // Set the new payload to the message context.
