### Why is this important?
Alternative descriptions are important for users whose browsers do not support the `<object>` element or the object's media type.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* If the `<object>` element is a Java applet, video, or image, add a text description using the `title` attribute
* **Or**, if the `<object>` element has a role of `application`, `document`, or `img`, add a text description using the `title`, `aria-label`, or `aria-labelledby` attribute
For example:
```
<object classid="java:Press.class" width="500" height="500"
title="Java applet: how temperature affects pressure">
<applet code="java:Press.class" width="500" height="500">
As temperature increases the velocity of the molecules in the balloon...
</applet>
</object>
```
