As far as I can tell, the statement in the XBL spec is the same as in the 
SVG spec. But in any case, the XBL spec's negative statement is not 
normative, it's just descriptive (and a consequence of the previous 
statement, which, as requested above, is now normative).

I don't understand why the <iframe> example looks like an exception. It 
isn't intended to look like one.
