UBL-DT-22
What does UBL-DT-22 mean? Language local identifier attribute should not be present
Why did my invoice fail UBL-DT-22?
The languageLocaleID attribute should not be present on text elements. Like languageID, locale metadata on free text is outside the EN 16931 core model and triggers a warning. Send plain text content only.
