The isValid function also takes an optional 'context' parameter which is an
array of all the values submitted.
public function isValid($value, $context = null)
{
if(($context['box1'] + $context['box2'] + $context['box3']) > $someValue)
{
// error
}
}
Any mention of this seems to have vanished from the docs, however - I'll
file a bug report.
