Technique H46:Using noembed with embed

Description

The objective of this technique is to provide alternative content for the embed element in a noembed element. The noembed is rendered only if the embed is not supported. While it can be positioned anywhere on the page, it is a good idea to include it as a child element of embed so that it is clear to assistive technologies that a text alternative is associated with the embed element it describes.

Examples

Example 1: noembed is provided inside an embed 

<embed src="../movies/history_of_rome.mov"
  height="60" width="144" autostart="false">
  <noembed>
    <a href="../transcripts/transcript_history_rome.htm">Transcript of "The history of Rome"</a>
  </noembed>
</embed>

Example 2: noembed is provided beside an embed 

<embed src="moviename.swf" width="100" height="80"
  pluginspage="http://example.com/shockwave/download/" />
<noembed>
  <img alt="Still from Movie" src="moviename.gif" 
    width="100" height="80" />
</noembed>;

Applicability

Documents that load plugins with the embed element.
