1037 fn:json-to-xml: 'number-parser' option

Issue: #1037

I think the intent is fine, but I find the sentence "The result is obtained by invoking [fn:string] for the result of the function call." confusing.

I would suggest wording along the lines: "The string value of the number element generated in the result will be the value obtained by calling the supplied function, and then converting its result to a string by calling fn:string#1".
