    Text has to scale from a desktop to a mobile device for example.
    Otherwise it isn't accessible.

That is scope. I presumed a wrong scope.
  What other devices are in scope for this definition?


    > That leaves usability under a heading of total width, Universal 
    > Accessibility.
    
    Eh? I don't understand. 

From the diagram? That's the only two remaining domains.

    
    Usability + Accessibility = Universal Accessibility?

IMHO, universal accessibility is a vision, goal, or something
I'd  find hard to define without further scope. So I'll disagree
with that definition, rationale being that its unscoped.



    

    I would 
    like authors to write simple well XHTML web pages that can 
    be mangled by the user agent for the user's needs. I am 
    probably going back to the "write once for all" philosophy.

A part of the goal? It sells accessibility, but is very hard
for the range of published material, across the range of devices
and the range of disabilities.


    
    
    I hope you don't expect authors to cater for particular 
    devices.
I don't expect anything. You mention mobile devices above?

    Once again a author should write "accessible" 
    content, and rely on the device's user agent to cater for 
    alternative input and output.

I'd disagree with that. I think that dumps the burden on 
the user agent. Dear browser, please make this content accessible.
Its a shared responsibility, author, recipient with appropriate tools IMHO.
    
    > summary.
    > Who is your audience for this definition?
    
    Authors.
Of what content, class of content or at least something to clarify?
Map authors? 
Simple text authors? 
Wiring diagram authors?
  


    
    > What media are you addressing?
    
    The Web.

<grin/> And from the earlier comment re devices, what class of recipient
device?
PC? PDA? mobile phone? Other devices to come as business transactions move
webwards?


    
    Maybe I am trying to get at here that there should be 
    clearer distinction between authors and user agents responsibility.

And transport, and device capability, and recipient information user
understanding.


    
    I mean who has the disability? The user agent, the device, 
    the technology, the author or the user nowadays? :)

Going round in circles I guess, but which disability?
Is ignorance a disability? The author who simply states that
blind people can't get at web content, can they? Simply can't 
comprehend it. I've met such people. 


HTH ( a little :-)
