Yeeps. That later sentence seems wrong, particularly when you look at the "alt" attribute:

2.5.2.  "alt" Attribute

   Alternative text description of the artwork (which is more than just
   a summary or caption).  When the art comes from the "src" attribute
   and the format of that artwork supports alternate text, the
   alternative text comes from the text of the artwork itself, not from
   this attribute.  The contents of this attribute are important to
   readers who are visually impaired, as well as those reading on
   devices that cannot show the artwork well, or at all.
