BR-TMP-4BT-123 "Supporting document description" (ram:Name) darf innerhalb von "Additional supporting documents" (BG-24) höchstens einmal vorkommen.

Official rule text

Within one supporting document (BG-24) the document description (BT-123) may appear at most once — a warning, not an error. Several names for the same attachment are not allowed — a second document needs a second BG-24 group.

Severity: Warning
Applies to: CII
Rule set: v2026-08-31
Checked on: 4 September 2026

Written and checked against the official KoSIT rule set by Dmytro Yalanskyi, NormAPI.

Why does BR-TMP-4 happen?

This happens when several attachments are written into one group instead of one group per attachment: the loop appends ram:Name repeatedly to the same node. The recipient can then no longer tell which name belongs to which file.

What the validator checks

The expression the official KoSIT rule set evaluates — not paraphrased, but read from the Schematron file it ships.

CII: count(ram:Name) <= 1

Source: rule set v2026-08-31

How do you fix BR-TMP-4?

Emit one ram:AdditionalReferencedDocument group per attachment, each with exactly one ram:Name. BR-TMP-4 is the correctly scoped version of CII-SR-475: the CEN rule hangs off ram:ApplicableHeaderTradeAgreement and so counts the names of every 916 document together. Two attachments with one name each are fine by BR-TMP-4 and trip CII-SR-475 — though both report only a warning.

In the XML

A CII fragment — the rule applies to that syntax only.
