No, <iframe> is a browser window, it has to just be usable as a browser 
window. The fallback for <iframe> is only for browsers that don't support 
<iframe> at all. It would break the Web to do otherwise.

Let me rephrase. <embed> should use a plugin to display the requested 
data. If there is no plugin available, it should display a placeholder, 
IIRC. (What exactly a plugin is is not defined by HTML5.)

(Since <embed> wasn't in HTML4 we have to be careful with it, browser 
compatibility here is even more important than with other elements.)
