Doh, didn't know about RequireIfMissing's existence and ended up
implementing something to do just that a long time ago... :(
I'ts basically a metaclass you can assign to any Validator class so
it will only 'kick-in' if some field in the form is checked. It uses
the 'state' argument to pass state along the schema so that field can
be at any level of nesting (IIRC).
If the example you're providing isn't working email me and I'll send
you what I've got. Sorry but cannot help on RequireIfMissing because,
as I've said, just know that it existed ;)
