This test case is intended to pass because there is text above the image that identifies it and conveys the same information. Only the image itself is tested, not the image map.

“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.
The test case passes (line 15, column 7) the following success criterion: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.html#text-equiv-all.
The image has no text description associated with it, but the text above it may be sufficient.
The img element has an empty alt attribute but the text above the image may be sufficient.
This test case does not map to a WCAG 2.0 technique or failure.
(In Mozilla 1.7.3 and Firefox 1.0, the map does not work if the map element has only an id and no name attribute.)
The test case passes (line 15, column 7) the following success criterion: http://www.w3.org/TR/2006/WD-WCAG20-20060427/guidelines.html#text-equiv-all.
The image has no text description associated with it, but the text above it may be sufficient. User testing provided the following results: users of screenreaders, Braille displays or magnification software had no problems understanding what was in the image.
The img element has an empty alt attribute but the text above the image may be sufficient.
(In Mozilla 1.7.3 and Firefox 1.0, the map does not work if the map element has only an id and no name attribute.)

The test case needs review before it can be established if it passes or fails the following success criterion: http://www.w3.org/TR/2006/WD-WCAG20-20050630/#text-equiv-informative. The code that causes doubt can be found at line 15, column 7.
