Well, I have my reading cut out for me. Thanks for posting.
>>Note that by allowing a hyperlink inside another one
Wow! That makes perfect sense,but it's kind of crazy.
OT - in theory HTML 5 allows links to surround block elements (H1 + div + etc), but I have not found this to work well in browsers and when I look at it in Firebug, it renders as if I had multiple links around multiple elements. So I wouldn't count on the link within a link functionality working anytime too soon.
>>G5: Allowing users to complete an activity without any time limit
I don't think banks, Paypal, etc are ever going to allow that, at least not in the broadest sense. I suppose the imperative here is to stipulate that as long as the user keeps her session alive with some sort of key stroke or something, the session should not time out. And even though I have no real accessibility issues (colorblind), I do find that very often transactions time out on me, so meeting this guideline would improve things for many visitors as long as it can be done securely.
