FWIW the 'animation' element in SVG has a definition problem.  Unlike 
video, audio, or image, which talk about a media type with 
characteristics, where the actual format is defined by the MIME type 
of the thing embedded, the animation element refers directly to SVG.

Further, it's not clear to me what the media-type difference is from 
video or audio:  a timed presentation, possibly with indefinite 
duration or fixed duration, possibly with visual appearance, and 
possibly with user interaction.  These are all true of <video>;  what 
extra semantics does <animation> bring (apart from the unfortunate 
restriction above)?
