Part of Item: Common Failures
Comment Type: TE
Comment (Including rationale for any proposed change):
While there are common failures about _inappropriate_ text alternatives (F30) and omitting the alt attribute _for decorative non-text content_, namely img and applet per test procedure (F38), there is no common failure about not having a text alternative for img, area, input[@type=\'image\'] in general (alt attribute).

If there is no alt attribute, F30 does not apply. If the non-text content is not decorative only, F38 does not apply. 

applet and object is a different case. As the text alternative is the text content of these elements (or in case of applet the alt attribute), there is always at least an empty text alternative.

Proposed Change:
Add a common failure about omitting the alt attribute for img, area, input[@type=\'image\'] in general.
