.IX Header "DESCRIPTION"
Applying this trait to your attribute makes it's initialization tolerant of
of undef.  If you specify the value of undef to any of the attributes they
will not be initialized (or will be set to the default, if applicable).
Effectively behaving as if you had not provided a value at all.
