--- Comment #2 from Michael Dyck <jmdyck@ibiblio.org> ---
Presumably, the Function Call terminology is meant to parallel the definition
of functions in the Data Model, where the implementation of a function is
either "a host language expression" or "an implementation-dependent function
implementation".

And anyway, the Function Call text does immediately say "(e.g., it is a
built-in function ...". It seems like that should have been enough to answer
the original question.

That's correct. You'll find the same thing for every other kind of expression:
its writeup doesn't say where its dynamic context comes from.

In general, an expression E1's dynamic context "comes from" whatever expression
E0 caused E1 to be evaluated, and it's the same dynamic context unless there's
something about *E0* that makes it different. So it's the writeup for E0's kind
of expression that would talk about that difference.

E.g., with
    let $x := 1 return f($x)
it's the section for Let Expressions, not the one for Function Calls, that
tells you how to construct the dynamic context for f($x).
