Rules

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

Primary Rules

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 11, column 101.

Functional Outcome

The image has a short text description as well as a long one.

Technical Comment

The object element has a title attribute and a long description inside its content.

This test is identical to xhtml1_wcag2_20050630_1.1_l1_sc1_029 but the img's title attribute is moved to the object element, the fallback image was removed and thereby also the longdesc link. Since browsers do not necessarily provide access to the content of the object if the object can be displayed, it is not certain that the long description is available to users.

(Internet Explorer does not support object, to the test will not work in this browser.)
