Shouldn't match, I would think.

What does it mean for a legend to be disabled?

That seems like a discussion for the HTML working group, not this one.

The former can have values sent to the server, though.

Actually, in HTML in particular they're more or less identical for most 
controls.  But in any case, that's an HTML issue, not a CSS one.

Uh...  It's true pretty much by definition at the moment.  Though again, 
the goal is to move to a different definition, one where the markup 
language will define what's in these states.

Yes, and since the idea of "inheritable attribute" is not defined in 
HTML it means absolutely nothing.  You could just as well say that the 
"disabled" attribute is grozflzsnork.  Again, take that up with the HTML WG.

Nothing to do with inheritability.  They just do what I said, based on 
code inspection.

Seriously, you need to get away from HTML here, especially because HTML 
doesn't actually define how this stuff should work for it (unlike, say, 
XForms, which does).
