title: is a select option with no value, valid?
body: <p>Let's say that I have this select. If I post this, the value would be: city 1, city 2, city 3 and city 4. I don't want to give them a value, because the value is the same as the option-name.</p>
  
  <p>Is this okay?</p>
  
  <pre><code>&lt;select&gt;
      &lt;option&gt;City 1&lt;/option&gt;
      &lt;option&gt;City 2&lt;/option&gt;
      &lt;option&gt;City 3&lt;/option&gt;
      &lt;option&gt;City 4&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
