The media elements that make up a media composition are treated as a single, unified media element. For example, if a media composition encapsulates a sequence of videos, the CompositeElement will behave as if it's a single VideoElement, but one which plays several videos in sequence.
Because a CompositeElement maintains a list of MediaElement children, any of which may be CompositeElements themselves, a media composition can be expressed as a tree structure.
Typically a CompositeElement is not instantiated directly but instead is used as the base class for creating specific types of media compositions.
