In the markup, it can't. But in CSS, it's pretty much assumed that all 
elements have a namspace, and in the DOM, there is a namespace attribute 
on nodes that can be given a value.

The paragraph above (slightly clarified in more recent drafts) is just 
saying that as far as those mechanisms go, HTML should be assumed to have 
the XHTML namespace (which, as you point out, is pretty much what UAs do 
anyway, to some extent).

Sending the XML variant of Web Apps or Web Forms as text/html is invalid 
anyway, so we don't need to define that particularly IMHO. In fact frankly 
I'd rather we supported <foo//.

Why would it be better? The whole point is that <command/> would be used 
for the cases where you don't want anything to appear in legacy UAs. If 
you do want something to appear, well you can use <button>.
