--- Comment #3 from Michael Kay <mike@saxonica.com> ---
We've recently changed the definition of "extension function" in XSLT to "a
named function added to the static or dynamic context using mechanisms outside
the scope of this specification", with non-normative notes to explain what this
means in practice.

In XQuery there's the complication that external function may be declared in
the prolog, but there can also be functions that aren't declared. If the term
"external function" is restricted to those that are declared in this way, then
what are the undeclared ones called? How about some alignment - call them
"extension functions".
