[basex-talk] XQuery Prolog with serialization settings - basex "Unknown option 'basex'?

Greetings!

I have the following in the prolog of an XQuery:

declare namespace output = 'http://www.w3.org/2010/xslt-xquery-serialization'; declare option output:method 'basex'; declare option output:basex 'indent=yes, newline=\n';

I'm following the example at: https://docs.basex.org/wiki/Serialization for CSV, reasoning the same form should work for basex.

Sadly, BaseX 10.4 on Debian reports:

[XQST0109] Unknown option 'basex

Is it because basex isn't in the namespace of 'http://www.w3.org/2010/xslt-xquery-serialization'; ?

OK so I change the namespace to http://tm.durusau.net and it runs!

Sadly not applying the requested formatting.

Some guidance on serialization please?

Thanks!
