No, it can also be raised during static analysis: "if an implementation can
determine during the static analysis phase that an expression, if evaluated,
would necessarily raise a type error or a dynamic error, the implementation may
(but is not required to) report that error during the static analysis phase."
[XQuery 2.3.1].

I believe it's not obliged to raise any error (for this condition) during
static analysis, but if it does, the error must be XQDY0084.

However, since the Formal Semantics document does not specify errors by name, I
believe this issue would be more appropriately filed/resolved under the
"XQuery" component.
