Thank you, Christian! The problem is that this way I lose the base URI! The only way how to retain it which I am aware of would be the insertion of @xml:base, but this amounts to a change of the document I may not be authorized to do by the context. Is there any way how to change a document (as modified copy, not via copy/modify/return) and retain or control the base URI of the result, without inserting @xml:base?

You may need choose the classic element constructor for that: let $doc := <doc><a/></doc>return element { node-name($doc) } { $doc/@*, namespace xyz { 'https://basex.org/ns' }, $doc/node()} Hope this helps,ChristianVon: Hans-Juergen Rennau via BaseX-Talk basex-talk@mailman.uni-konstanz.de Gesendet: Samstag, 2.
