SMIL was considered, but several factors led to us deciding not to use it
in HTML5:
- We got strong feedback from existing producers of video on the Web that
their experience with SMIL had been universally disappointing.
- The SMIL model is based around XML and namespaces, which isn't really
compatible with text/html and HTML5.
- SMIL's conceptual model wasn't a good fit for the requirements we had
in mind for <video>.

For XML content you can use <object> or <iframe> and the contentDocument
attribute to obtain the Document object.
