I understood the question that we need a way to specify whether the item
is countable or not.

I don't think the Option 2 is a good idea. I understand the "type" is a
language-independent type for inter-module communication. We do not need
to add a new kind of integer type only to indicate the item is countable.

Instead, I think it is good to indicate the value is countable or not as
an attribute like Option 1 / Option 3. The attribute can be used not
only for integer type but also real type. Personally I prefer Option 1
for supporting co-existence of countable items and uncountable items.

By the way, I couldn't find any documentation for "named_set" type. Is
there any place which describes data format other than
