I quoth:

This is to what I was referring.

You also wrote:

 | for the alternative content), or 'none' (none).

To which I did not allude.

 |
 | We could/should do that with CSS!

Depends on how you do it, actually.

 | You're missing the point here entirely: I'm using this to replace navbars,
 | and other content in the DOM styled as optional. That's a valid WAI use that

As for missing the point, see above.
As for this use not currently implementable in XHTML, see
   http://www.w3.org/TR/WCAG10-HTML-TECHS/#group-bypass

What do you want to replace the content with, though? Would you give me an
example? I'm not entirely sure I understand the (second) purpose of this 'alt'.

 | If you are refering to the 'content' property, I am suggesting we have an
 | explicit 'alt' property as well.

I am referring to the ability of (X)HTML to specify its own alternate content
for unrenderable media.

 | So explain the CSS content: property then! If that's a style, then so is
 | this...

em:before, em:after {content: '/'}

This sentence contains an /emphasized/ word.
