bug: Alt text should identify image class when relevant

Hi all,


any thoughts on this bug would be appreciated:

*Bug 23207* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=23207> - Alt
text should identify image class when relevant

The particular case that is being called out is when there is an logo that
is the sole content of a link, and thus the alt text is the link text:

code example[1]

<a href="http://w3.org">
  <img src="images/w3c_home.png" width="72" height="48" *alt="W3C web site"*>
  </a>

the bug reporter is suggesting that because the image is a logo this
information should be included in the text.

My thinking is that as the primary purpose of the image in the context it
is being used is as link content, the alt text should be a brief
description of the link target only.
