Yeh, you can get away with it if you're careful, but it's currently not  
proper.

True. But I don't personally omit that stuff in a regular page. I don't  
think I would in an embedded page either.

Yes, Ian's example showed that @doc is just for fragment markup where  
standards mode would always be applied and, because it's interpreted as  
html, HTML, HEAD, BODY (and perhaps TITLE) would be implied and the markup  
would always end up inside BODY. And, if you make use of implicit closings  
etc. you can keep things much shorter.

However, I still like the idea of explicitly specifying full markup for  
the embedded doc like you can with src="data:". I also like being able to  
do src="data:application/xml," in text/html pages.
