title: How can I hide a parameter's defaultValue in Swagger UI?
body: <p>I place the Swagger formatting directly in my Ruby API source and use Source2Swagger to create the documentation: </p>
  
  <pre><code># ~ a = my_api.apis.add
  # ~ a.set :path =&gt; "/my_api/{application_key}"
  # ~ op = a.operations.add
  # ~ op.set :httpMethod =&gt; "GET", :nickname =&gt; "getmyapi"
  # ~ op.summary = "Get stuff from My API"
  # ~ op.parameters.add :name =&gt; "application_key", :description =&gt; "User authentication token", :dataType =&gt; "string", :allowMultiple =&gt; false, :required =&gt; false, :paramType =&gt; "path", :defaultValue =&gt; "1234567890"
  # ~ op.responseMessages.add :message =&gt; "No stuff found", :code =&gt; 204
  # ~ op.responseMessages.add :message =&gt; "API down", :code =&gt; 500
  #
  get '/my_api/?:application_key?', :provides =&gt; :json do
    Do stuff...
  end
  </code></pre>
  
  <p>The "application_key" is not required, but users need to know the option when the API goes live.  As you can see above, I was asked to supply a default value for internal use (please don't ask why :-)) but I would still like to hide the default value of the parameter when displaying the documentation.  Is this possible?</p>
