The ePub 3.0 document content model is HTML5.  HTML5 UA's will be used
to render ePub publications, embedded in hardware or software eBook
readers.  Note that ePub is a container (like ZIP) that contains HTML5
content and associated resources, which may include any audio and
video referenced in the content.  In the eBook world, content is
downloaded and read on a local device.
