Applets included in this document do not have corresponding valid textual descriptions. A valid description is a string value for CONTENT that is not any of the following:

• An empty string ("")
• A blank string with one or more spaces (" ")
• The name of the file containing the applet
• The size of the applet file

Add a content to the APPLET tag.

The textual description should convey the same information as the applet, and it should explain the role the applet plays on the page: why it is there, what it represents, how it presents the information.

Here are cases where applets may not run:

• Some users view the page on PDAs and cellular phones that cannot execute applets
• Some applets use libraries written for a specific operating system such as Windows, MacOS, or Linux
• Some users of graphical browsers disable applets for security reasons

Provide a text equivalent describing the behavior of the applet using the ALT attribute and the content in the APPLET tag. This enables the content to transform easily for those user agents that only support one of the two mechanisms (ALT or content).
