BR-TMP-5BT-125 "Attached document" (ram:AttachmentBinaryObject) darf innerhalb von "Additional Supporting documents" (BG-24) höchstens einmal vorkommen.

Official rule text

Within one supporting document (BG-24) there may be at most one embedded attachment (BT-125) — a warning, not an error. Two files in the same group are not allowed, even though the schema technically permits them.

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-5 happen?

Several attachments get written into a single group, as on BR-TMP-4. Since each group carries only one description and one document type, the recipient loses the link between file and description.

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:AttachmentBinaryObject) <= 1

Source: rule set v2026-08-31

How do you fix BR-TMP-5?

Emit one ram:AdditionalReferencedDocument group per file, each with exactly one ram:AttachmentBinaryObject including its mimeCode and filename. The filenames have to differ, which is BR-DE-22's job. BR-TMP-5 is the correctly scoped version of CII-SR-476: the CEN rule hangs off ram:ApplicableHeaderTradeAgreement and counts the files of every 916 document together, so two cleanly separated attachments set it off.

In the XML

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