Summary of Issue: For longer time-outs, would not a cntrol that removes automatic refresh meet the SC?
Comment (Including rationale for any proposed change):
The Failure test just looks for meta http-equiv with value "refresh"  and content  > 0. I can see a scenario where the value of content is high (say, 1200 = 20 minutes) and a control is available to extend or turn off auto-refresh (e.g., via DOM scripting of the meta http-eqiv content attribute). In that case, it seems to me that SC 2.2.1 would be met. Would F41 nit need to be updated to reflect that option, also in the test procedure?

Proposed Change:
Not sure - if my argument holds, the test would need to check whether a page actually get refreshed (either by inspecting the content value or, if it is done server-side, by waiting (how long a wait is sensible I am not sure, 20 mins?), and, if the page is found to refresh, look out for a control to extend or turn off the time limit. If a refresh takes place and there is a working control giving uders enough time to locate it, the Failure would not apply.
