At least for HTML, the only ways I know of to "create a complete change of 
main content through an automatic refresh" are to use meta-refresh or 
script.  Both can be disabled in browsers.  Are there other technologies 
that have these issues?  If so, we could create a general technique about 
it.  If not, then I don't think this is a common failure for HTML, and I 
propose that we delete it.


One issue with automatic updates that the user can or cannot disable is 
that they need to happen before the user knows that there is an auomatic 
update in place. The first automatic update is definitely a change of 
context that the user did not request. That seems to be an argument for 
keeping the failure. Right?

Note that meta-refresh can be implemented either with the HTML meta element 
or with the non-standard HTTP Refresh header (see 
for 2.2.1: if you remove the URL part, you get a 'server-side' refresh - 
although it's really the browser that requests the refresh).
