Search fieldset

[anormand]

Expected behaviour

When assistive technologies encounter the search form they should identify it as having a role of search

Actual behaviour

There is a fieldset without a legend. The fieldset isn't required because there is only one input field.

Steps to reproduce

1. Go to http://www.unimelb.edu.au/accessibility
2. View source
3. Source will be as follows:

   <form class="search" method="get" action="https://search.unimelb.edu.au">
   <fieldset>
   <div class="inline attached">
     <span class="fill">
       <input aria-label="Search the University" id="header_q" type="search" placeholder="Search the University" name="q">
     </span>
     <span>
       <button class="inline-button" type="submit">
         <span class="small icon--hide-label" data-icon="search" data-bound="true"><svg role="img" class="icon" focusable="3"><use></use></svg><div class="icon-label">Go</div></span>
       </button>
     </span>
   </div>
   </fieldset>
   <a class="page-header-icon" href="http://www.unimelb.edu.au/accessibility/_nocache#" data-bound="true"><svg role="img" class="icon"><use></use></svg> Close</a>
   </form>

Steps to remedy defect

2. Delete the fieldset

   <form class="search" method="get" action="https://search.unimelb.edu.au" role="search">
   <div class="inline attached">
