[xsl] [XPath 3.0] How to do partial function application on the min() function?

["Costello, Roger L." <costello@xxxxxxxxx>]

Hi Folks,

I would like to fix one argument of the min() function to 2 and leave the
other argument undefined, thus producing a partially applied function. Then, I
would like to give the partially applied function a value. Here's what I
tried:

            let $min2 := min((?,2))
            return $min2(3)

I get this error: Unexpected token "?" in path expression

What's the correct way to accomplish this?
