the one thing i can think of that would actually be more efficient that
what we've got now is to do a union using Object between IValidator
and IValidator[] and manage the array by hand. that would actually
get rid of all node objects in cases where we have more than 2. also,
the array object should be smaller, when trimmed to size than the current
node object.

ooh. actually this is incorrect too.
for 1, it's the object directly
for 2, there is only ONE node (because of left/right pointers!)
for N, there are N - 1 node objects
and the cases of 1 or 2 validators is really the majority.

Well, right now you're doing exactly what LinkedList does. You're
wrapping every object in a node and including two object references.
Where's the space savings? You could get rid of half the objects by
using an array and essentially reimplementing ArrayList. The downside
here is that if I add a string validator to a RequiredTextField, I
have no gaurantees that the value I get will be non-null.
I do like what you did with the booleans though. That's tight. :)
