Technologies are markup languages or data formats. If the technology is a markup language, “features” refers to elements and attributes.

This test case is intended to fail because the image and the image map areas have no text alternatives.
Automatic evaluation.
“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.
The test case fails the following success criterion at line 15, column 7: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.html#text-equiv-all.
The test case fails the following success criterion at line 18, column 46: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.html#text-equiv-all.
The test case fails the following success criterion at line 19, column 47: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.html#text-equiv-all.
The test case fails the following success criterion at line 20, column 47: 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. However, none of the areas in the image map has a text description.
The img element has an empty alt attribute but the text above the image may be sufficient.
However, since each of the area elements in the map element has an alt attribute, this case does not pass.
This test case is identical to sc1.1.1_l1_009, except that the alt attributes of the area elements are now empty.
This test case does not map to a WCAG 2.0 technique or failure.
(In Mozilla 1.7.3, SeaMonkey 1.1, Firefox 1.0, 1.5 and 2.0, the map does not work if the map element has only an id and no name attribute.)
