DescriptionDocument containing an object element that embeds an audio-only object. There is no descriptive label nor a (longer) description associated with the object.

Technologies and Features

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

XHTML™ 1.0 The Extensible HyperText Markup Language (Second Edition)

Feature: object (namespace: http://www.w3.org/1999/xhtml) .

Technical specification: Generic inclusion: the OBJECT element .

Test Data

Purpose

The test case is intended to fail because there is no text description of the audio-only content enclosed in the object. This test is only for descriptive text labels, not for synchronized alternatives (guidelines 1.2) or changes of context (success criterion 3.2.5).

Test Modes

Automatic evaluation.

Test Files

Test file.

TCDL Data

sc1.1.1_l1_054 (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 10, column 3: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.html#text-equiv-all.

Functional Outcome

There is no descriptive text alternative for the audio.

Technical Comment

sc1.1.1_l1_056 contains a variation on this test case, but the object element has a closing tag instead of using empty element syntax.

On a computer with Windows XP, Windows Media Player 9 and Apple Quicktime 7.1.3, the following browser behaviour has been observed: Firefox 2.0 plays the sound but does not display a player, Opera 9.0 displays a Windows Media Player interface and plays the sound, Internet Explorer 6 (with Service Pack 2) display a Windows Media Player interface but plays the sound in a separate Windows Media Player window.

This test case does not map to a WCAG 2.0 technique or failure.
