title: Is there a legitimate use-case for putting a fieldset outside of a form?
body: <p>I was recently corrected, and according to the HTML4 DTD, it is legitimate to use a <code>fieldset</code> outside of a <code>form</code>:
  <a href="http://www.w3.org/TR/html401/sgml/dtd.html#block" rel="nofollow noreferrer">http://www.w3.org/TR/html401/sgml/dtd.html#block</a></p>
  
  <p>Previously I had not known this, and wonder if anyone can think of a legitimate use case for doing so.  I feel like using one to decorate would be frowned upon by most designers.  So is there a legitimate use case, or <strong>can you link to a site where this has been found appropriate and used as such?</strong></p>
