Animations appear on the screen only; the animated text prints, but the animation effect does not.
This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in TextPatternIdentifiers.
UI Automation clients get the value of the attribute by calling GetAttributeValue.
Values for this attribute are of type AnimationStyle. The default value is None.
