The term "identical" in Functions and Operators is defined in the context of
saying whether two function calls return the same result, but if we want it as
a defined term, perhaps it should be defined with a wider scope.

The XDM is indeed quite explicit on this:

Each node has a unique identity. Every node in an instance of the data model is
unique: identical to itself, and not identical to any other node. (Atomic
values do not have identity; every instance of the value “5” as an integer is
identical to every other instance of the value “5” as an integer.)

Indeed, that paragraph seems quite clear to me.
