Description

Reported on the help forum on this site today by Nikolay Ognyanov

The XQuery compiler accepts a comma after the last parameter in function declarations. Here is an example which compiles and runs under Saxon-PE 9.5.0.2 :

xquery version "1.0";

declare function local:foo($a,)

{

$a

};

local:foo(1)

The parameter list is defined as

ParamList ::= Param ("," Param)*

So this is clearly a bug albeit a minor one.
