XPath 2.0 leaves it to the host language to define which functions are
supported; it merely provides a repertoire to choose from:

(a) functions in the fn namespace in F+O
(b) constructors for built-in types
(c) constructors for user-defined types
(d) functions defined by the host language spec e.g. XSLT or XForms
(e) user-defined functions written in XQuery or XSLT
(f) functions defined and provided by the implementor
(g) extension/external user-written functions written e.g. in Java or C#

I don't think there is a simple way of saying that the minimum for XML Schema
is (a)+(b).
