           Summary: Constraint validation ought to match a radio group; that
                    is, if any checkbox in the group is checked, the whole
                    control is valid.  Not only would this change make the
                    API consistent for mutually-exclusive (radio) and
                    mutually-inexclusive (checkbox) widget

Comment:
Constraint validation ought to match a radio group; that is, if any checkbox
in the group is checked, the whole control is valid.  Not only would this
change make the API consistent for mutually-exclusive (radio) and
mutually-inexclusive (checkbox) widgets, but it has a broader set of
applications.  It is the rare case that someone would want to force a box to
be checked with the validation API, but enforcing that at least one box in a
group is checked is the exact sort of application that this API was designed
for.  If someone wants to force a box to be checked, he can always put it in
its own group.
