Accessibility and extending Flash

With the extensibility layer in Flash, developers can create extensions that enable advanced authoring. This lets third-party companies develop extensions that involve accessibility. You have several options for validating your SWF files or adding captions.

For example, a validation tool can examine your SWF file for missing descriptions. It checks to see if a description is added for a group of instances, or if text has a label for the instance, and tells you about any problems. The tool also examines the reading order in your SWF file, and finds all instances that must be specified. You can specify reading order by using a dialog box after the SWF file is analyzed.
