SMIL 2.0 is a significant extension to the very popular SMIL 1.0 Language. Among the key new features of the language are:
Support for media transitions: you can apply visual transitions to all visually rendered media (including images, text and video), based on a new structured transitions module.
Support for animations: you can move objects during the presentation and change colors of displayed areas.
Support for event-based activation: along with new scheduling primitives, SMIL 2.0 allows object to start relative to user events (such as mouse clicks) or the start/end of other objects in the presentation
Support for advanced layout functionality: SMIL 2.0 provides methods for structuring the presentation's layout as a hierarchy of regions. This gives you more design control and makes animating groups of objects easy and efficient.
New Custom Test Attributes: one of the most powerful features of SMIL 1.0 was the ability to control content based on System Test Attributes. These attributes are extended in SMIL 2, and augmented with user-defined test attributes that allow you unprecedented control over what gets rendered.
SMIL-2.0 also expands existing timing, layout, and synchronization control. You can read all about the features in the language in the 500 page specification produced by the World Wide Web Consortium (W3C).
