Hi there,
So I had an action to look at comprehensive and feasibility. I did  
these by first taking a broad sweep over all the principles and then  
drilling down into each guideline.

So comprehensive wise I wonder why we don't just have principle 2 as  
'technology' as opposed to assistive technology - why do we not use  
the more general case, which includes assistive technology, but does  
not limit the principle to it.

I also think principle 2 contains quite a few overlaps in the  
guidelines that could be harmonised (when we get to it). One thing  
that does worry me is 2.10 - how do we define 'timely' and as it is a  
AA is it OK for the UA to not provide timely exchanges at A and if  
this is the case what does this say about dynamic content provision  
through the api which must have timely updates to be understandable.

On the whole I think principle 3 is good however 3.5 worries me - as  
I don't think this is feasible in any productive way - what algorithm  
would you use to give a coherent repair? In addition should we even  
attempt 3.5.2 if adding alt would effect the text flow with no  
benefit? My biggest problem here is with 3.8 - This seems to be an OS  
activity and control of pitch etc seems to be an AT activity - I  
think this asks for too much and is not feasible to expect this  
control to be provided - I would suggest a replacement that there is  
an option to apply a user defined audio Style Sheet though.

I think principle 4 is comprehensive and feasible although I'm still  
not sure if 4.2 is really feasible. Finally, principle 5 seems  
comprehensive and feasible. My only concern is that we don't make any  
assertion about how easy it should be to get to the additional  
functionality that the UAAG implies.
