IonNull clone()
       throws UnknownSymbolException
```
    Description copied from interface: IonValue
    
    Creates a copy of this value and all of its children. The cloned value may use the same shared symbol tables, but it will have an independent local symbol table if necessary. The cloned value will be modifiable regardless of whether this instance IonValue.isReadOnly().
    The cloned value will be created in the context of the same ValueFactory as this instance; if you want a copy using a different factory, then use ValueFactory.clone(IonValue) instead.

    clone in interface IonValue
    
    Throws:
    
    UnknownSymbolException - if any part of this value has unknown text but known Sid for its field name, annotation or symbol.
