Description

XSLT3 Test case higher-order-functions-060 is failing. No error is reported when the function fn:string-length#1 is passed to an argument whose expected type is function(xs:string) as xs:string.

The cause of the problem is that the evaluate() method of XdmFunction.CoercedFunction checks and converts the supplied arguments, but applies no checking to the result.
