Re: [basex-talk] Joining a varying number of information sources (with XQuery)?

Could you please get specific and provide real use cases and examples?

An example application was published already with the XQuery 3.1 specification for the combination of information from three documents. https://www.w3.org/TR/2017/REC-xquery-31-20170321/#id-joins Would you occasionally like to join significantly more entities (with for clauses according to known relationships)?
