ePub 3 slideshow

[odedta]

Depending on the capabilities of the User's Reading System, they will see one of the following renditions of the slideshow:

If the Reading System supports the native slideshow format, it will render a rotating set of images as specified in slideshow.xml.

If the Reading System cannot support the slideshow media type but supports scripting, it can check the bindings element in the Package Document for a scripted fallback. There it will find a reference to the item element containing the handler document (impl.xhtml). The Reading System can now load this document to render a JavaScripted equivalent of the slideshow (source not shown).

If the Reading System does not support the slideshow media type and also does not support scripting, it will use the fallback images specified in the object element to show a static set of all the images.

This is what it says about slideshows in the idpf's specifications.
Which device support bindings and which arn't? Assuming I have a working JavaScript that makes a slideshow, how do i use it as a fallback?

Working example perhaps?
