[basex-talk] One of the map element causes SEPM0017 error

[Arkadiusz Bok]

Hi,
I'm trying to run one of unchanged code example from book "XQuery: 
Search Across a Variety of XML Data 2nd Edition" from publisher O'Reilly 
Media.

|(: XQuery by Priscilla Walmsley (c) 2016 Priscilla Walmsley:) |

|(:Example 13-4 Serialization parameters in a map :) xquery version 
"3.1"; declare namespace prod = "http://datypic.com/prod";; let $map := 
map { "method": "xml", "version": "1.0", "indent": true(), 
"cdata-section-elements": (xs:QName("prod:desc"),xs:QName("prod:name")), 
"use-character-maps": map { "«":"<%", "»":">%" } } let $element := 
<prod:name>Fleece Pullover</prod:name> return serialize($element,$map) |

I'm using BaseX 9.3.2 to do this. But when I'm trying to run code, I get 
error:

|Stopped at C:/Users/Arek/AppData/Local/Temp/example1304.xqy, 16/17: 
[SEPM0017] item() expected, xs:QName+ found: 
(Q{http://datypic.com/prod}desc, Q{http://datypic.com/prod}name). |

When i remove 9 line with /cdata-section-elements/ element, code runs. 
Whether is it problem with XQuery implementation or with code?
