### Describe the usage question you have. Please include as many useful
details as possible.
Using the following schema to represent a nullable integer tuple type, how
does one write the tuple `NULL` and differentiate it from `(NULL, NULL)`? I
know the latter can be written by writing integers with def level 0, but I'm
not sure about the former.
```
message schema {
optional group a (LIST) {
optional int f1;
optional int f2;
}
}
```
If it's not possible, are there any methods (ex. recommended schemas,
columns, metadata) which are commonly used in this situation? I was thinking
about adding an additional bool field `isNull` to deal with the problem, but
I'm not sure if it's the best way.
