   <h6>Guidance for markup generators</h6>
 
   <p>Markup generators (such as WYSIWYG authoring tools) should,
   wherever possible, obtain alternative text from their
   users. However, it is recognised that in many cases, this will not
   be possible.</p>
 
+  <p>For images that are the sole contents of links, markup generators
+  should examine the link target to determine the title of the target,
+  or the URL of the target, and use information obtained in this
+  manner as the alternative text.</p>
+
   <p>As a last resort, implementors should either set the <code
   title="attr-img-alt">alt</code> attribute to the empty string, under
   the assumption that the image is a purely decorative image that
   doesn't add any information but is still specific to the surrounding
   content, or omit the <code title="attr-img-alt">alt</code> attribute
   altogther, under the assumption that the image is a key part of the
   content.</p>
 
-  <p>Markup generators should generally avoid using the image's file
-  name as the alternative text.</p>
+  <p>Markup generators should generally avoid using the image's own
+  file name as the alternative text.</p>
