<h2>WCAG Considerations</h2>

In the context of this specification, this text alternative is intended primarily to support users of the subtitles who cannot see images. Since the images of an Image Profile subtitle document usually represent subtitle or caption text, the guidelines for authoring text equivalent strings given at <span class='sec-no'>Images of text</span> of [[HTML5]] are appropriate.</p>
