title: Is it possible to a swagger parameter name have variables?
body: <p>I'm documenting an API using swagger, and one of the parameters have a variable in it's name (eg: <code>param[VARIABLE]=value</code>). It will be sent in form, like this:</p>
  
  <pre><code>param[VAR1]=value1&amp;param[VAR2]=value2
  </code></pre>
  
  <p>I think the parameter definition would be something like:</p>
  
  <pre><code>parameters:
    - name: 'param[{var}]'
      in: formData
      description: 'Parameter description'
      required: true
      type: string
  </code></pre>
  
  <p>Is it possible to implement this in swagger? </p>
