Actually, in this case, it could say "this installs a background 
process that launches at boot and has root privileges" or "this adds 
the frobotz extension to Microsoft Office", and so on.  The installer 
can work out what pieces it is putting where.

Similarly the filename is probably more informative than "this is an 
image", and maybe where it comes from, how large it is, and so on. 
You don't even have to do image analysis.

I'm not saying this is the right way to go, mind you.  I'm just 
arguing that the work of accessibility is NOT done when the spec. 
permits, or has features that would support, good accessibility; 
it's done when good accessibility actually happens in practice.  And 
writing a spec. that achieves that is quite tricky and involves 
subtleties about the way people think and behave.

My perception is that some of the push-back to proposals is not 
because people don't support accessibility, but because people fear 
that proposals are too complex to be widely supported, or would end 
up (as in the example above) possibly even worsening the position, in 
practice.

Our goal is a web that has good accessibility, not just a 
specification which supported something which didn't end up happening.
