Secondary Rule (WCAG 2.0 - June 2005 Working Draft)

The test case passes (line 5, column 5) the following success criterion: http://www.w3.org/TR/2006/WD-WCAG20-20050630/#visual-audio-contrast-dis-audio.

Technical Comment

The proprietary bgsound element plays a sound that can be stopped by activating IE's UI stop control.

Microsoft introduced the bgsound element with Internet Explorer 2. The src attribute specifies the URL of the audio file (WAV, AU or MIDI); the loop attribute specifies the number of times the sound will play (positive integer or 'infinite'). Internet Explorer 4 also added support for the attributes balance, delay, and volume.

Secondary Rule (WCAG 2.0 - February 2005 Editor's Draft)

The test case fails the following success criterion at line 5, column 5: http://www.w3.org/WAI/GL/WCAG20/WD-WCAG20-20050211/#4.1_use-spec-document-backward-compat-violations.

Functional Outcome

The file is not valid.

Technical Comment

The bgsound element is not a legal element in (X)HTML, so the file does not validate.
