Thanks for your detail answer. What I gave to you is an exported output of BaseX database version 7.3.1 (old database) via Java application with BaseX version 8.6.7. I tried to export with BaseX version 7.3.1 with same db:export() XQuery, but it returns error
db:export("userdb", "/home/mascalan/", map { 'method': 'xml' }) Error when querying BaseX database 'Failed at querying the database, detail: Stopped at line 1, column 45: [XPST0003] Invalid key, simple expression expected. Check collection name and version are valid first.'. I think if I could export to you the XML of old database by BaseX version 7.3.1, you could see the http://localhost:8080/def/crs/OGC/0/_Temporal_template in the XML file which BaseX version 8.6.7 couldn't find to export (?)
