UBL-DT-27
What does UBL-DT-27 mean? Scheme Agency ID attribute should not be present
Why did my invoice fail UBL-DT-27?
The schemeAgencyID attribute should not be present on identifier elements in an EN 16931 UBL invoice. The core model qualifies identifiers with schemeID only (where a scheme is allowed); agency metadata is outside the model and triggers a warning. Remove the attribute.
