title: Add a link in the label of a Joomla form element
body: <p>I'm trying to add a link to a field in the joomla contact form. I'm trying to achieve this:</p>
  
  <pre><code>&lt;field name="contact_terms"
          type="checkbox"
          id="contact-terms"
          description=""
          label="I agree to &lt;a href='http://example.com/terms'&gt;Terms and Conditions&lt;/a&gt;"
          default="0"
          value="1"
          required="true"
      /&gt;
  </code></pre>
  
  <p>but it gives an error and I'm just very very new to joomla. How should it be done?</p>
