Test Data

Purpose

This test case is intended to fail because the image and the image map areas have no text alternatives.

Test Modes

Automatic evaluation.

Test Files

Test file.

TCDL Data

sc1.1.1_l1_024 (XML).

Rules

“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.

Primary Rules

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.

Functional Outcome

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.

Technical Comment

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.)
