+``if_missing``:
+      Typically when a field is missing the schema will raise an
+      error.  In that case no validation is run -- so things like
+      ``if_invalid`` won't be triggered.  This special attribute (if
+      set) will be used when the field is missing, and no error will
+      occur.  (``None`` or ``()`` are common values)
