Technique H46:Using noembed with embed

Obsolete

noembed is obsolete in the HTML Living Standard. Use object instead when fallback is necessary.

About this Technique

This technique is not referenced from any Understanding document.

This technique applies to documents that load plugins with the embed element.

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>

Tests

Procedure

  1. Check if embed element has a child noembed element
  2. Check if embed element has a noembed element that immediately follows it.

Expected Results

  • #1 is true or #2 is true
