Arguably the heading should be programmatically determinable as being 
part of the "context" (with regards to 2.4.4 Link Purpose (In Context)).

Because it's not possible for automated tools to unambiguously determine 
whether a checkbox/radio button's label is not sufficient. Not all 
checkboxes/radio buttons *need* a grouping label, if their label is 
explicit enough (or if any of the other possible ways of providing 
naming/labelling, like additional aria-label, aria-labelledby, 
aria-describedby, etc are being used).

For link lists, I'd say 2.4.4. provides some initial guidance at least. 
For other form controls, if the label/name of the control itself is not 
sufficient, then you're looking at a failure of 4.1.2 Name, Role, Value

There's a danger of lumping all sorts of things under 1.3.1 here. 
Sometimes a simple HTML heading is/should be sufficient, without 
requiring explicit association of all following links/form controls with 
that particular bit of heading text - though again this comes down to 
the individual situation.


p.s.: a small request to reduce duplicate/triplicate emails being fired 
at people on the list - when replying to a thread, would it be possible 
for people to edit the list of recipients so that, if it's a reply to 
the mailing list, it's just sent to the mailing list, rather than "Reply 
all" which then sends emails to both the list AND the person on the list 
you're responding to (and then, as the conversation continues and 
everybody else does a "Reply all", ends up with emails sent to half a 
dozen individuals on top of being sent to the list)?
