title: Is an empty element (such as <a href="#">) valid for accessibility purposes?
body: <p>I manage several websites that use a featured article scroller on their homepages, which allows the user to click a forward or back arrow in order to see the next article headline and blurb while remaining on the same page.</p>
  
  <p>I use WAVE's accessibility checker and any sites that have this particular plugin throw an error back because within the code there is an empty link, written as <code>&lt;a href="#"&gt;</code>.  Is there any way around this?  I've defined a <code>title</code> attribute but the <code>#</code> is causing the empty link error to still come up.</p>
  
  <p>Some places I've seen that this is perfectly acceptable and others claim this is a problem.  What's the actual answer and potential workaround?</p>
