Programmatically, a media element encapsulates a set of media traits and a state space. The media traits represent the capabilities of the media element and are dynamic in nature. At one moment in time a media element might be seekable, at another moment it might not be. For example, this could occur if the media element is a video sequence containing unskippable ads.
A media element operates on a media resource. For example, if the media element represents a video player, the media resource might encapsulate a URL to a video stream. If the media element represents a complex media composition, the media resource URL might be a document that references the multiple resources used in the media composition.
