> Comments from [~jamestaylor]: 
> The way we differentiate a null value now is by the value being an empty byte array (explicitly set to null) versus not being present (in which case we use the default value).
> This is encapsulated in the DefaultValueExpression.
> We'll need to tweak our encoding for this.
> One way would be to use a negative number for the offset.
