Detailed Description

Validates name/value pairs in param tags to be used in safe objects.

This will only allow name values it recognizes, and pre-fill certain attributes with required values.

Note

This class only supports Flash. In the future, Quicktime support may be added.

Warning

This class expects an injector to add the necessary parameters tags.
