** Description changed:

  Consider the following example Query:
  
-   import module namespace json = "http://www.zorba-xquery.com/modules/converters/json";;
-   import module namespace html = "http://www.zorba-xquery.com/modules/converters/html";;
-   declare namespace j = "http://john.snelson.org.uk/parsing-json-into-xquery";;
-   let $text := "<p>" || json:parse("{""text"":""Let's get it. \ud83d\udc4a""}")/j:pair[@name="text"]/text() || "</p>"
-   return html:parse($text)
+   import module namespace json = "http://www.zorba-xquery.com/modules/converters/json";;
+   import module namespace html = "http://www.zorba-xquery.com/modules/converters/html";;
+   declare namespace j = "http://john.snelson.org.uk/parsing-json-into-xquery";;
+   let $text := "<p>" || json:parse("{""text"":""Let's get it. \ud83d\udc4a""}")/j:pair[@name="text"]/text() || "</p>"
+   return html:parse($text)
  
  Problem:
  
  this query raises an error in file src/com/zorba-
  xquery/www/modules/converters/html.xq.src/tidy_wrapper.h function
  createHtmlItem(...) and returns an empty sequence. Yet, html:parse ()
- has return type document-node().
- 
+ has return type document-node() (not document-node()?). Therefore, it is
+ not allowed to return an empty-sequence.
