Another strategy you could use is:
class SuperSchema(Schema):
foo = Foo()
bar = Bar()
gnus = Gnus()
If Foo has a validator for, say, "email", then you need to name the
field "foo.email". I.e., every field starting with "foo." goes to
Foo, everything with "bar." goes to Bar, etc.
This is the intended way to reuse validation sets like this; multiple
subclasses are tricky and I can think of all too many reasons why they
wouldn't work.
