The alt element provides alternate text for an image. It is equivalent to the alt attribute on the image element; the attribute is deprecated, so the alt element should be used instead. As an element, alt provides direct text entry within an XML editor and is more easily accessed than an attribute for translation.
The markup for alt text within an image looks like this:
<image href="tip-ing.jpg"> <alt>Here's a Tip!</alt> </image>
