As I'm sure you realise, XPath 3.0 and XQuery 3.0 specs are built from a single
source so there's sometimes a tendency for XQuery things to "leak" into XPath.
(Tuples are another example).
Thanks for pointing it out, though I'm not sure if there's still time to fix it
before the Rec goes final.

In the XPath 3.0 Proposed Recommendation, section, 3.1.5.3 "Function
Coercion", http://www.w3.org/TR/xpath-30/#id-function-coercion
describes the properties of the function returned by the coercion in
the following bulleted list:
* name: The name of F .
* parameter names: The parameter names of F.
* signature: Annotations is set to the annotations of F.
TypedFunctionTest is set to the expected type.
* implementation: In effect, a FunctionBody that calls F, passing
it the parameters of this new function, in order.
* nonlocal variable bindings: An empty mapping.
The third bullet above in particular says:
"signature: Annotations is set to the annotations of F.
TypedFunctionTest is set to the expected type"
My question is: What are function annotations and why they are nowhere
defined in the document?
Note: The XQuery function that is used as example, does not contribute
to making this section more understandable -- on the contrary. Why do
the authors assume that anyone that uses XPath should know XQuery?
