The http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd requires an alt
attribute for images, and the HTML DTD shows a similar requirement:

<!ELEMENT img EMPTY>
<!ATTLIST img
  %attrs;
  src         %URI;          #REQUIRED
  alt         %Text;         #REQUIRED
  longdesc    %URI;          #IMPLIED
  height      %Length;       #IMPLIED
  width       %Length;       #IMPLIED
  usemap      %URI;          #IMPLIED
  ismap       (ismap)        #IMPLIED
