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 ...
My question is: What are function annotations and why they are nowhere
defined in the document?
Function annotations are defined in the Data Model spec as part of the
signature of a function value:
http://www.w3.org/TR/xpath-datamodel-30/#function-items
The data model spec also mentions that for XPath the annotations will always be
an empty set.
This is consistent with the statement in the XPath section on function coercion
which states that the annotations in the result function are the same as the
annotations in the input function.
So there's not actually a technical error in the spec; it's just not as helpful
as it might be.
