Context and Significance

This EN16931 core code-list rule only constrains the subject qualifier; the free-text note itself remains unrestricted.

Solution

In UBL, prefix the note with a UNCL4451 code between hashes, e.g. "#AAI#General information" or "#REG#..."; a free-text note without a code is also accepted.
