Changes vs D.96A
The UTILTS message is not published in directory D.96A. No "D.96A → D.16B" comparison line can therefore be produced — see the block below for details.
This message is not published in directory D.96A: it was introduced into the standard after that release and therefore has no historical baseline for comparison. The first directory indexed on ediverse.io sets the reference; later changes are then documented from one release to the next in subsequent directories.
Structural example
Minimal example of an UTILTS D.16B message with mandatory segments only. The goal is to show the exact version declared in UNH (UTILTS:D:16B:UN) — not to replicate a full business case.

UNZ+1+CTRL016001'Common errors
- Misaligned UNH tokens — The
UNH+...+UTILTS:D:16B:UNtoken must reflect exactly the directory in use — a mismatch between the UNH release and the release agreed with the partner is rejected by every strict validator. - Wrong UNT segment count — The value after
UNT+must include UNH and UNT themselves. By far the most common sender-side error, regardless of the directory in use. - Stale code lists — Between D.96A and D.16B, several code lists received new qualifiers (DTM status, RFF qualifier, NAD codes…). Reusing an older directory’s code tables triggers warnings or even rejections depending on the partner’s strict-conformance mode.
