Description Christian Gruen 2015-05-20 14:47:38 UTC
In the "Examples" section of fn:json-to-xml, it's a bit surprising to have code in the XSLT syntax. Maybe it could be replaced with the following equivalent example:

  let $jsonstr := unparsed-text('')
  let $options := map {
    'liberal': true(),
    'fallback': function($char as xs:string) as xs:string {
      let $c0chars := map {
      let $replacement := $c0chars($char)
      return if (exists($replacement))
        then $replacement
        else error(xs:QName('err:invalid-char'), 
          'Error: ' || $char || ' is not a terminal control char.')
  return json-to-xml($jsonstr, $options)

Thanks for the suggestion. The XSLT example was there because of my laziness when moving the spec from XSLT 3.0. I have adopted your revision, except to replace

let $x:=A let $y:=B return C


let $x:=A, $y:=B return C

to make it valid in XPath as well as XQuery.
