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.
