Checkpoint 1.1 - XML/XSLT
Allow authors to associate text descriptions with any non-text content (graphics, sound, multimedia, scripts, etc.)
XML Accessibility Guidelines
Guideline 1. Ensure that authors can associate multiple media objects as alternatives
If the XML grammar is defined too restrictively the author will not have the flexibility to provide alternative content for different user devices as needed for the target audiences.
Requirement
For all content defined in the XML grammar ensure that content alternatives are available to the user of the grammar
Techniques
For graphical objects include a text description element for use by the author if required. For example, in SVG, the <desc> element can be used to describe the graphic.
<svg width="6in" height="4.5in" viewBox="0 0 600 450">
<title>Network</title>
<desc>An example of a computer network based on a hub</desc>
</svg>
