[basex-talk] Issues with new json xml function and copy clause

I am having issues with the new json-to-xm functions with a copy clause. I would expect the following query to work: *let $json := '{"age":23,"name":"Bob"}'return copy $out := json-to-xml($json) modify delete node $out//*[@key='age'] return xml-to-json($out)* Instead I get an error when calling xml-to-json: [FOJS0006] Element 'map' has invalid namespace: ''. It appears the copy clause is dropping the namespace on the map object. Is this something I must manually prevent or a bug? Thanks for all your time. - James
