The any-of must take a function that has the type: (a -> a -> Boolean)

The type of *-is-in is ( a -> [a] -> Boolean), where a is a primitive
type, such as the type of function:string-is-in is:

(String -> [String] -> Boolean).

An application of string-is-in would be:

<Apply FunctionId="function:string-is-in">
    <AttributeValue DataType="....#string">Hello World<AttributeValue>
    <AttributeDesignator ....../>
</Apply>
