The following example in section 3.7 has undeclared definition of the function ext:sc. Also the syntax of the map constructor in the return statement is incorrect:


declare variable $languages := ("English", "Greek", "Latin");

declare function local:spellcheck($languages, $text)
{
  map:merge (
     map { "languages" : $languages },
     map { "raw" : $text  },

     for $l in $languages
     return { 
       $l : array {
         for $w in $text
         return ext:sc($l, $w)
       }
     }
  )
};
