Hi there Greg, and thanks for your thoughts on this one.

I can see where you're comming from on #1 however a quick dictionary 
search says
perceive |pərˈsēv|
verb [ trans. ]
1 become aware or conscious of (something); come to realize or 
understand : his mouth fell open as he perceived the truth | [with 
clause ] he was quick to perceive that there was little future in such 
arguments.
2 become aware of (something) by the use of one of the senses, esp. that 
of sight : he perceived the faintest of flushes creeping up her neck.
3 interpret or look on (someone or something) in a particular way; 
regard as : if Guy does not perceive himself as disabled, nobody else 
should | [ trans. ] some geographers perceive hydrology to be a separate 
field of scientific inquiry.

I was taking 1 and 3 as my definition while I think you are taking 2. In 
reality I think I'm fine with your take on this as 'become aware by the 
use of one of the senses' is probably what most people hold to be right. 
I mainly put this in to show that there is some ambiguity there.

I think your answers to my other questions are fine, but I think I'm 
beginning to think about the UAs and accessibility slightly differently. 
I'm increasingly beginning to think that accessibility is really about 
translation between forms of the same information, and control my the 
user of the way they interact with that information; in that the 
assistive technology is created for a specific user group and is made to 
translate and facilitate the interaction of a user group in a way which 
is natural for them.

It just so happens that a browser/user agent facilitates access to 
itself and the translation from HTML to rendering all in one package, 
and for a very specific user group. In this case, is it not more natural 
to make sure the common user agent facilitates both control and access 
of itself and the information it accesses by other intermediary 
technologies designed for other specific user groups. In this case 
guidelines which make sure this openness to intermediary technologies 
would be level A. I can also see that in some cases it could be 
advantageous for additional aspects of accessibility to be included 
within the user agent for users who may not require additional assistive 
or intermediary technologies and I would therefore say that any aspects 
of the user agent which added accessibility and assistive components 
within the common package could be AA. Finally I would see that 
functionality not provided, as standard, as part of the common user 
agent, but which would be very useful for different kinds of users via 
their intermediary technologies would be Triple-A.

This may sound initially outlandish, but I think that we are in danger 
of making manufacturers of user agents into manufactures of user 
agent-assistive technology hybrids; as opposed to user agents with open 
access and control for use by other intermediary tools more suited to 
the user, and built by developers who understand their specific user group.

Of course I could be wrong on this, or my thinking could change as 
replies and argumentation appear in this forum, but at this point I'm 
still worried, and so any more insight you might have would be greatly 
appreciated.

Cheers
Si.
