To cut myself off here, I did just find this <http://www.w3.org/Bugs/Public/show_bug.cgi?id=7278

To quote Ian: "The idea is just to provide a basic fallback that will  
be acceptable in legacy browsers", but that's not really what the spec  
says.

The spec says: "The *recommended* way of giving the value is to  
include it as contents of the element". (Emphasis mine)

So the spec recommends using the textContent to specify the value, the  
comment on the ticket seems to imply that's a last resort for legacy  
browsers and you should really use @value. Very few of the examples  
use @value though, further lending to the idea that it's best practice  
not to use it.

Perhaps the language of the spec needs fixing?

At the very least, could we get an example in that big examples  
section that uses a comma and @value?
ex.
    <!-- Localized with comma decimal separator -->
    <meter value="0.75">0,75</meter>
