| Title | Alternative text for two nested objects with image map inside innermost object |
|---|---|
| Description | A document with an object element in an image map. The object element embeds an image in PNG format, and
contains another object element that embeds the GIF version of the same image. This second object elment contains only the image map.
The object elements do not have a title attribute or any other text alternative except the alt attributes of the map's area elements.

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

It is not entirely clear if this test case fails. The innermost object element does not contain an img element with an alt attribute, but it contains the image map, and each area in the image map has an alt attribute that conveys the same information as the area, and the image itself is identified in the text above it.
In addition, browser support for the object element may determine if this test case is accessible or not. Internet Explorer (version 6 or earlier) has weak or no support for the object element.
End user.
“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.
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 10, column 6.

The image has a text description in the sentence preceding it.
The object element has an img element with an alt attribute as a fallback .
Since there is no direct text alternative, it is not entirely clear if this code is accessible.
This test case is identical to xhtml1_wcag2_20050630_1.1_l1_sc1_014, except that the fallback image has been removed from the innermost object element.
(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.)
(Internet Explorer does not support object so the test does not work in this browser.)
