Using ops:switch with HTML5
|Component:||Open Publication Structure (OPS)|
It is not clear how to use ops:switch with HTML 5 elements (which belong to the same namespace as XHTML and do not define XHTML module, as far as I can tell). See http://blog.threepress.org/2009/11/15/using-html5-video-in-epub/
I'm proposing that the switch element needs to change, but I'm also suggesting that it's not within scope for a maintenance release, and should be set to "Future Consideration".
