Documentation for Export/Import file currently is outdated and needs to be updated.

Without deeper investigation there are couple places to be updated.
https://www.zabbix.com/documentation/current/manual/xml_export_import/hosts:

• inventory_mode is no longer under the inventory block. It is part of host object itself.
• details for interfaces no longer have "snmpv3_" prefix.
• macro type "vault" is missing.

Most likely there are more.
All supported versions needs to need to be checked separately.
