Mapping from ATD to "validate"
*)
type validate_repr = (string option * bool)
(* (opt_v, b)
is obtained by analyzing all available type definitions.
The first value opt_v is the optional local validator
coming from an ATD annotation (see `Local).
The second value b is true iff the data doesn't need scanning.
There are four cases:
opt_v = None && b = true => no validation is needed at all
opt_v = None && b = false => validators must be called on some
sub-fields of the data
opt_v <> None && b = true => the given validator must be called
but there's no need to look into
the sub-fields
opt_v <> None && b = false => the given validator must be called
in addition to scanning sub-fields
