Namespace of the ZUGFeRD metadata is not permitted (BR-HYBRID-04)
- Standard: ZUGFeRD
- Severity: error
- Affected fields: BT-24
Meaning
The extension schema in the XMP metadata names a namespace (URI). Only the five URIs that ZUGFeRD and Factur-X defined across their versions are permitted. The version part of the URI does not follow the format version.
Possible causes
- The URI was typed by hand and contains a typo.
- The URI was derived from the format version instead of being copied verbatim.
- A URI from a different specification was used.
How to fix it
- Update your invoicing software, or send this result to its vendor.
- Copy the URI verbatim from your library's XMP template; from ZUGFeRD 2.1 it is urn:factur-x:pdfa:CrossIndustryDocument:invoice:1p0#.
